Tetro Duel

Race a bot at falling blocks. Clear two or more rows at once and you send garbage rows up the bot's well; it does the same to you. First to twenty-five rows wins, and a full well loses at once.

How to play

  1. You and the bot each have a well and each get the same set of pieces in a different order. Move and turn your pieces to clear full rows.
  2. Clear two rows at once to send one garbage row to the bot, three rows to send two, and four rows to send four. Garbage rows have one gap in them.
  3. Rows you send show up as an incoming warning on the bot's side, and the other way round. Clearing rows yourself cancels incoming garbage first.
  4. The first side to clear 25 rows wins. If a well fills to the top first, that side loses.

Tips and strategy

  • Singles do not hurt the bot. A double or better does, so build a flat surface and clear rows two at a time.
  • Garbage rows rise from the bottom with one gap each. Line the gap up with a vertical piece to clear several at once.
  • Watch the incoming number. If it is high, clear rows now to cancel it before it lands.
  • The bot places a piece every few seconds and rarely clears more than a pair, so steady play wins.

FAQ

Can the bot cheat?
No. It uses the same pieces and rules, picks its landing spot from the board and sometimes picks the second best spot instead of the best.
What counts as winning?
Reaching 25 cleared rows before the bot does, or the bot's well filling up first.
What cancels garbage?
Any rows you clear. They are taken off the incoming garbage before it rises.
