Sea Treasure

Nothing on this board slides on its own. You lift an item off the seabed, set it down where you want it, and three of a kind standing together score and vanish. Placement, not swapping, is the whole verb.

Because any reachable item can go anywhere, the constraints are ones you build yourself. There is no legal-move rule to blame when the board tightens — every awkward stack was assembled by an earlier decision, which makes a good run feel authored rather than dealt.

Cool underwater colours keep shells, stones and salvage distinguishable while your hand is over them, which matters more in a drag game than in a tap game: the piece you are holding hides part of the board.

The measure is a number and the run ends when the space does. Short sessions, instant restarts, nothing carried between them.

1. Survey the seabed before lifting anything.
2. Drag an item and set it beside two more of its kind.
3. Gather three or more to score and clear the space.
4. Guard your open squares — the run ends when they run out.

Pick the destination first, then the piece. Lifting an item while still deciding is what leaves it stranded in the centre, and the centre is the ground you need free when the board fills.
