Logic
Block Fit
Clear lines, plan ahead
Drag pieces from the tray onto a nine-by-nine board. Fill a row, a column, or a three-by-three square and it clears. The run only ends when nothing in your tray fits anywhere.
There's no timer. The pressure is space itself. Gems appear on the board and clearing through them pays extra, while a hold slot lets you bank an awkward piece for the right moment. Greedy placements feel wonderful right up until they wall you in.
