Blind Builder

Work together to fill the glowing Shadow with Tetris pieces — but nobody can see where teammates are placing theirs until the big Reveal!

How to Play

Host opens the game on a TV or large screen — a QR code appears for players to join.

Each player scans the code and joins the room. The host sets difficulty and number of Shadows.

The Shadow appears on the TV. Players race to grab a Tetris piece from the shared stock.

Everyone secretly moves and rotates their piece on their phone — nobody can see each other's placement until the Reveal!

Pieces fly to their positions. Overlaps get thrown back! Fill every Shadow in the fewest rounds — together. Blame each other for overlaps.
