Tap + / − on each seat to set its squids; seats holding squids show them on the felt. Stake = what this hand's squid is worth to that seat in BB (what's at risk beyond the pot). Each seat also shows its win % for this hand (the chance of winning the pot and taking the squid). Tap a seat for details. After a hand, give the winner +, then tap Next hand ⟳ and every position name rotates one seat (squids and the "me" marker move with the players). Blue = receive, orange = pay.
Win rates are not equal: position and how much the squid matters to each player both change them, and the stakes with them. The presets above are free for everyone; other rules are a Pro feature.
