Circuit Tetris

Circuit Tetris is a browser-based block-stacking game that focuses on completing horizontal lines using circuit-board themed pieces. Unlike standard Tetris clones, this version strips away complex hold mechanics and speeds up the pace for quick sessions. The standout feature is the auto-merge mechanic, which clears lines the moment you place the correct piece without requiring a separate drop action.

You click or tap to rotate the falling circuit segments and tap again to drop them instantly into the grid. The core loop involves watching the preview shape, deciding where it fits in the current mess of blocks, and reacting before the piece descends too far. Every turn requires you to choose between filling a gap to build a solid foundation or going for a risky clear to reduce the stack height. There are no power-ups or holds, so every mistake stays on the board until you manually fix it with subsequent pieces.

This game suits casual players who need a ten-minute distraction and don't want to learn complicated button layouts. Tip: Prioritize keeping the center column clear in the first minute, as it gives you the most flexibility for placing wider horizontal pieces later.
