About Reefhold
Reefhold is a three-minute placement puzzle. You are given buildings one at a time — huts, fields, docks — and you put them somewhere on a small island. Every building scores from what ends up next to it, so a hut wants neighbours and a dock wants water, and the score you finish with is the sum of every decision about adjacency you made along the way.
There is no undo and no map to scout. You see the piece in your hand and the next one coming, which is exactly enough to plan one move ahead and never enough to plan three, and the island is small enough that by the halfway point every remaining space is a compromise.
The island is generated, so no two runs give you the same coastline, and the coastline is most of the puzzle — where the water reaches decides which half of your buildings are worth anything. A run takes three minutes and asking for one more is the intended reaction.
It is the smallest game on this site: one HTML file, 63 KB, everything drawn procedurally. It loads before you have finished reading this sentence.
Controls
- Click or tap a tile
- Select where the building goes

- Commit it. Nothing is placed until you do
- The next-piece display
- Shows what is coming, which is the only lookahead you get
- The speaker icon
- Mute and unmute; the setting is remembered
Tips
- Spend the first few pieces defining edges rather than filling the middle. The middle will fill itself; the edges decide what the middle is worth.
- A dock away from water is not a small loss, it is a zero. Check the coastline before the neighbours.
- Leave one awkward tile deliberately empty. There is always a piece later that only works there.
- The run you should compare yourself to is your own on a similar island — the generator can hand you a coastline that caps the score before you place anything.
What changed
- Sound now stops properly when the game is paused by the page around it. This was broken since release and fixed later than the other games here.
Reefhold is ours — code and art, with nothing borrowed and nothing to clear with anybody else. It can be licensed for your portal.
