Rings and Dot!

A hypercasual color-matching puzzle on tic-tac-toe's 3×3 board. Instead of X's and O's, you stack concentric colored rings in each cell. Line up three of the same color in a row, column, or diagonal — big ring, small ring, or the center dot, size never matters — and that line clears for points. Chain several clears in one move for escalating combo multipliers. There's no win state, just an endless run and a new high score to chase.
