Players place physical wooden blocks into a grid, with some blocks having notches that match the blocks above or below them. Each block's placement affects the blocks below and above it, with some combinations causing blocks to fall or stand still.
The goal is to clear horizontal or vertical lines of blocks without making them fall into the bottom of the grid, which, if it happens, loses a player's turn. Strategically rotating and placing blocks to line up and match shapes is key.
The game requires players to think ahead and balance short-term and long-term objectives. No downloads or registration are required, and the game can be played directly in the browser.
