Gobblet

Nesting tic-tac-toe, you (cyan) versus a tactical CPU (amber). It's three-in-a-row on a 3×3 board — but every piece comes in three sizes and a bigger piece can gobble (cover) a smaller one, yours or the enemy's. Only the top of each stack counts. You each hold two Smalls, two Mediums and two Larges. On your turn you either place a new piece (onto an empty cell or a smaller top) or pick up one of your exposed pieces and move it. The twist: lifting a gobbler can uncover an enemy piece — and if that completes their row, you lose. Memory, bluff and tic-tac-toe in one.
