Reefhold

An island rises out of the water and you are given four huts. Where they go is the whole game.

Every building scores from what is already next to it. Huts like company. Fields want open ground and hate being crowded. Docks only pay on the coast, and the coast is finite. The number appears on the tile before you commit, so nothing is ever a guess — it is a choice between two goods.

Score enough and you are offered another pack, and a decision: which of two building types your island actually wants. The threshold climbs faster than your board does, and after five or six packs the island is full, the run is over, and the next island is nothing like this one.

• Two taps to place: one to preview the score, one to commit
• Buildings that read off their neighbours, so the board is a puzzle rather than a grid
• A new island every run, coast on every side
