Pocket Archipelago

Pack every land cell with the fixed-orientation pieces. There is NO rotation. Piece diagrams show their3×3 footprint from the top-left anchor; dots are water. Choose a piece, tap an anchor, inspect the white footprint, then Place. Red dashes mean overlap or shore crossing. A piece's anchor may be water if the shape itself leaves that corner empty.

Lift a selected occupied piece to rearrange it without disturbing others. Undo reverses the latest placement or lift. Survey runs an exact packing check: it suggests a legal continuation without placing it, or warns that your current arrangement has no complete tiling and needs lifting/undo. Hints are optional and counted, not penalized with a loss.

Three islands grow from4 to5 to6 pieces. Every expedition's connected coast is constructed from a valid tiling, so it is solvable before your placements. Complete an island to unlock the next. Retry repeats this island; New expedition changes the coast and starts island1. All pieces remain fixed orientation. Arrow keys focus cells; native buttons support touch/keyboard.
