Build a biome by placing tiles, ensuring it doesn't break apart.

Update: While not intended for mobile (it was built specifically for web browsers on a computer), we have found that this build is actually working fairly well all the way through on newer mobiles as long as it is horizontal. If on a mobile device, then double-tap to place. Keep in mind though, it was formatted for computer screens and that's what it works best on, not mobile. Cheers!


  • Build your biome by filling the board with tiles!
  • Each tile is either a terrain tile (River, Forest, Desert, etc) or a developed tile (Farm, Nuclear Plant, Geothermal Plant, etc.)
  • Each turn, you have to choose one out of three tiles shown, to add to the board.
  • A tile may be only placed adjacent to another tile.
  • Tiles also have their own unique conditions for placement.
  • Each tile placed has a specific impact on its neighbors, and vice-versa. Choose and place tiles with care.
  • At the end of each turn, if the net impact on a tile from its neighbors is more than or equal to its total health (4), the tile breaks, and is removed from the board.
  • Any tile that is not connected to the 'Start' tile by a path of adjacent tiles will break.
  • If the active percentage (fraction of tiles placed that are still on the board) falls below the threshold for that level at any time, the world collapses and you lose.
  • Handle progressively harder challenges each level, with higher active thresholds.
  • Progress is saved, so if you lose you can restart from the same level.


  • Click on a tile choice to select it.
  • Now click on any of the highlighted squares to place the tile on that square.
  • Hover on any tile to view its placement restrictions and impact from other tiles.

I could play this all day! It took me a second to figure out how to play, but once I figured it out I loved the strategy it took to play it. Reminds me of "Minesweeper" and the board game "Betrayal at House on the Hill".

Very encouraging to know :) Glad to hear you enjoyed the game. Thanks!


Going full screen on your game cuts off some tooltips (win11). I really like it though. Very original. And the music is chill.


Thank you for the feedback and thank you for playing!
