Swapblocku

Swapblocku is a sudoku-inspired game where you take turns placing shaped pieces onto a 9x9 grid and try to clear lines and squares to score the most points possible before you can't place anymore!

In a unique take on the block puzzle genre, it adds the ability to play against an AI player or other humans online—as well as being able to rewind time to review past turns!
