Falling-block battle: same pieces, send rows, outlast them. The winner takes both stakes.
Same pieces, at the same timeBoth stacks get the same pieces from a 3 second count. Clear lines to send junk rows to your opponent: doubles, triples, quads, spins, combos and back-to-backs send more.
Last one standingTop out and the round is theirs. Pieces fall faster every 30 seconds and attacks grow every minute; if both are up after 5 minutes, more rows sent wins, then the score.
