How to play Custom Tetris?
Classic falling-block puzzling with a twist: you can tweak the rules. Tetromino pieces drop from the top — rotate and slide them so each one fits cleanly, and a full horizontal row clears and scores. Beyond the standard game you can adjust spawn rules, gravity speed, and the pool of shapes to build your own variant. Stack to the top and it is game over.
- Move — Left / right arrows

Keep your stack flat and low. A bumpy surface traps gaps that you cannot clear without the exact piece.
Leave one column open for line pieces and clear several rows at once for a much bigger score bonus.
When the stack creeps up, drop pieces flat to buy time instead of forcing a risky multi-line setup.
