Hakkeyoi, Nokotta! Step into the ring.
Slambo! is a sumo-themed hand management card game where the goal is simple: push your opponents out of bounds without losing your own footing. On your turn, play a card from your hand — blue cards raise the balance, red cards lower it. Force any opponent above 10 or below 0 and you've scored a SLAMBO!
If both players exhaust their hands without anyone being knocked out, the referee calls a rematch. Collect three shame cards and you're out of the tournament. Last wrestler standing wins.
That's the whole game — and it fits in a box the size of a card deck. Part of Allplay's Tiny Box line, Slambo! is richly illustrated with real sumo moves, easy enough to hand to anyone aged 6 and up, and ready to play with zero setup in about five minutes. Fast, fun, and genuinely tense in the final cards of each hand.
