Isles of Drought

Whats all this about - Designing a simple browser based multiplayer board game with a fantasy setting.

This has been in the hard disk for some time, waiting for me to fix here and there, add some artwork and refine some ideas. While still not complete as there are few things are missing (like spells and items section) and it could benefit from couple more artwork  but I guess its good to post instead of letting it rot within cobwebs.

isles of Drought - floating islands chained together


I would like to remind that Isles of Drought is designed to be a browser based game. Meaning it is meant to progress slowly so people can log in from their browsers during different times a day and take their turns. 

Another aim is to keep things simple. There are a lot of things that can be added like tons of different races, different skills, items, more complex mechanics and so on but for a browser based experience I would prefer a game which is easier to learn and simple to play rather than experiencing tons of different stuff squeezed into a single game.

Highlights of this game should be;
  • Browser based game that can be played from anywhere with custom pace and speed
  • Multiplayer game with a computer controlled "wild card" enemy (the undead)
  • 16 different races with 2 different skills each
  • Simple combat and economy rules for easy browser based experience

  2. Game Setup
  3. Gameplay
  4. Races
  5. Winning and Losing
  6. Conclusion


Did not spend much time on this as the game is not story based. However it would be nice if there was some lore behind the game and its denizens. 

Floating Isles is an alternative world made by the high-father as a heaven for different races to live and prosper without disturbing each other. The isles float above the clouds powered by various mana crystals. The races living on these isles collect and use these mana crystals as resource to keep their islands afloat. There is enough crystals to live happily forever so there is no reason for any race to assault the other. Everyone is happy and full of joy until the High father turns it's interest from the floating islands. Slowly these mana crystals start to become scarce. "The age of Drought" plagues these lands as every race finds itself in the blink of destruction and rushes to harvest as much mana as possible. With decreasing mana, the isles begin to lose power and some parts start to crumble.

So its a game about various fantasy races killing each other to harvest mana and keep their parts of the island floating.

Game Setup

As it is a multiplayer browser game, the pace will be slower compared to most other games. However i dont like games that force you to take a turn and come back in 5-10 hours time. Game speed should depend on the choice of the host. If I can take 10 turns per day why should I have to wait for a 10 hour game? I can just join (or host) a game with 10 minute turns etc.

Probably ideal game speeds should vary from 5 minutes per turn (fast) to 24 hours per turn (super slow) and players should be in control of their speed and pace by voting during multiplayer games 

(See gameplay section below for better understanding of terms)

The game map is divided into several isles, and each isle is divided into regions with a castle in the center. These castles connect to each other castles in the centers of other islands via floating bridges. Some regions may also contain extra items and other types of loot or resource bonus.

Map settings are straightforward stuff like;
- starting height / health of regions (low med high random) - random by default
- percent of resources per region (low med high) - med by default
- army recruitment delay (set time / turn limit)
- undeads (on / off) - on by default
- speed and pace (set time / turn limit)
- fog (on / off) - on by default
- seasons (on / off / delay) - on by default

Should be on by default, can be toggled off before game starts. With the arrival of the age of drought, floating isles where covered in black shroud. Shroud Covers the entire map in black fog, reveals as armies explore.

Should be on by default, every set number of turns season will change and winter will come to the floating island. (bit strange to have snow when you float over the clouds but whatever :) winter will cause units to move slower and resource output will be halved for the duration of winter.

- set season on / off,
- set season delay
- if delay = x turns then roll dice 1D6 = meaning every x + 1 to 6 days seasons will change between winter and summer.

Rather straightforward stuff;
1- create map (random seed or selected) depending on size desired
2- add player starting castles depending on the race chosen by each player.
3- seed map with towns and castles belonging to random npc races
4- seed regions with resource bonus and items

isles of drought - UI concepts


Map consists of a castle (node) joining the tiles around them to form a region. Production and resource collection is made by these towns or castles while armies move from node to node using the roads that connect the nodes (calling them bridges would be more accurate) to other nodes.

isles of drought - tiles

These floating tiles have different (random? set by the player before game starts?) levels of altitude. 5 being the highest while 1 the lowest. Every time tiles take damage (by harvest, spells or whatever reason) they sink by 1. If a tile reaches 0 that tile crumbles into the abyss below. Any resource on the tile is also destroyed with it. Roads or bridges aren't effected by such damage and cannot be destroyed. There is no way to disconnect a node.


There are two types of resources found in the islands. Gold and Mana. Gold is used for everything as a generic resource while mana is used for specific race related stuff. Collecting resources is done at the beginning of each turn as an automated progress. Every town or castle controlled by a player collects the resources from the tiles in their region

Regular collection is the primary way of gathering resources, done automatically (end turn, every 5 minutes, 5 hours whatever) by default unless the player interferes and commands the castle to use the "harvest" command. With regular collection method the castles collect a small number of resources from their regions without causing any damage to the tiles.

When the player uses harvest, sages and priests in the castle cast powerful magic spells to gain a resource bonus from the area. These harvesting spells are so powerful that they spoil the unity of the floating isles in their regions, causing all tiles to sink down by 1 level. When used a couple of times it makes all tiles in the region to fall into the abyss. These fallen tiles do not provide resource bonus anymore.

isles of drought - harvest vs regular gathering

Various bonuses can be found on some tiles:
- Castle - every region has a castle in the center. 
- Empty region (most common).
- Gold mine - provides gold bonus to region
- Mana rifts - provides mana bonus to region (same colour mana as the rift)
- Ruins - can be explored for random bonus (mana, gold or artifacts - ruins can also have hidden enemy encounters or could be deserted)

isles of drought - tile examples

Every region has a castle (node) in the center

Castles produce resources (gold + mana colour of the race occupying.) Capturing a settlement will grant the control of the entire region around it.  

Castles produce armies (army type of the race living occupying - so a human settlement can only produce human army) 

Castles have levels from 1 to 5.  A level 1 castle collects low amount of resource from regions around it and provide less defense but increases with each upgrade. Upgrading each level costs resources and time / turns.
Castles also allow the players to use the "harvest" command. Harvest order collects double the resources from the region but will have a negative effect on the soil of the tiles in the region and will cause the land to become unstable and crumble, making impossible to collect resources from the region. This can be used as an economic boost or an offensive tactic. (Offensive if you capture an enemy castle and start harvesting to damage the soil so the enemy wont be able to use the region even if they recapture.) 

Undead can turn castles into "tomb of souls" that will destroy the region around it and start producing large number of undead units each turn (minute, hour, whatever) If recaptured by a player, the Tomb of souls will be destroyed so the spawning of undead armies will stop but the castle cannot be rebuilt. It starts acting as an empty node.     

Movement is done from castle to castle (node to node), armies move using the floating bridges that connect islands. Regional tiles around the castles do not effect movement. These regions are for harvesting only.

It will take time to travel from castle to castle (node to node). (its a browser based game so time limits can vary from 5 hours to 5 minutes, 5 turns or a single turn depending on the game speed chosen before game start.)

A battle will take place when two opposing armies meet on a road (bridge) or a node. If the armies meet on the node the defender will benefit from terrain / town bonus while If they meet on a road (or bridge) the attacker or defender will not receive any terrain bonus.

Roughly unit stats should be as follows;
  • Cost - how much gold or mana required to produce 
  • Health - hit points
  • Attack - combat value
  • Initiative - shows who attacks first, higher means faster. value should be between 1 to 10 (can effect movement on map?)
  • Active - always active ability
  • Passive - on / off. passive skills that require mana to activate and have a cool down after each use.
Combat is handled instantly once two armies reach each other. Procedure is as follows:

1) check the initiatives of both armies.
2) roll bonus 1D6 dice for both armies to add randomness (optional?)
3) apply item / artifact / spell bonus if any
4) whoever has higher initiative total attacks first. (becomes attacker)
-  ATTACKER strikes -
5) deduct attacker's total "attack" value from defenders "health" value
- DEFENDER retaliates - (even if its dead)
6) deduct defender "attack" value from attackers "health" value 
- if both parties are still alive -
7) repeat 5 to 6 until an army is destroyed. (health value reaches 0)

  • step 2 is totally optional. some people enjoy a little bit of randomness instead of relying on direct maths.  It also helps greatly to resolve "who goes first" if two armies have the same initiative
isles of drought - combat

Armies occupying the same nodes can be merged together if they are from the same race (human army with human army, elven with elven etc.) When armies are merged their health is multiplied.

So if a human army has 120 hp and it merges with another human army with 120 hp they will become a single army of 240 hp with the most experienced unit as the leader. Artifacts and items will also  be kept with the new leader.

If a 120 hp human army merges with a 50 hp human army, the newly merged units hit point would be 170 hp and so on.

kill defenders on a castle (node) to take over the entire region.

Units level up as they gain xp from combat. Each level bestows additional damage, HP or initiative to the units.

New armies can be recruited from castles (nodes) once per day (or whatever time limit is set for "recruitment delay") Damaged armies can be  healed back to full health but healing costs gold and mana (cheaper then buying a new army)


Each player picks one of the following spheres of magic before the game starts.  (blue, green, white, red) and a starting race that belongs to the mana sphere chosen. 

Depending on their choice they will be given a starting castle that can produce the armies of the race they have selected. Also the player gains access to the spells offered by the sphere.

Each race has an active (free) ability which they can always benefit and a passive skill which needs to be activated (with a mana cost and cooldown to use again).  These abilities will either affect the unit itself, the region they stand, a radius around the unit or the neighboring regions.

Some races may be slightly unbalanced but it would have been awkward if every race was perfectly balanced turning things into chess. Players may see this balance issue as a way to make their game harder or easier by picking stronger or weaker races.  Plus the only proper way to maintain balance in these kinds of games is to keep playing and testing and this is only the concept phase, making it only possible to balance on theory.

Winning and Losing


Player wins the game if all opposing players are destroyed.

Player loses the game when he doesn't have any castles left.

Undead do not count as an opposing player.



A simple and casual browser-based game with easy to learn, hard to master turn based wargame mechanics, lots of data sheets and server side operations. Best suited for playing in the office :)
