Goal: complete all five stacks, each built from rank 1 up to 10.
The story:Rock crushes Scissors & Lizard Β· Paper covers Rock, disproves Savant Β· Scissors cut Paper, decapitate Lizard Β· Lizard eats Paper, poisons Savant Β· Savant vaporizes Rock, smashes Scissors. Every card shows its matchups: green icons = what it defeats, red icons = what defeats it.
Modes:Counterstack β mixed-suit Battle Stacks, and every card played anywhere must defeat the card beneath it. Suit Arenas β each stack collects one suit 1β10; tableau still plays by defeat. Alternating β suit Arenas, but tableau chains must alternate: a win link (βΌ), then a loss link (β²), then a winβ¦ Rush A / B β playtest variants: a 12-card face-down Reserve (top card playable), one play space per suit (5), random shuffles via Reshuffle. A uses suit Arenas, B uses Battle Stacks. Countercell Ξ² β every card dealt face-up in ten columns with four free cells (park any single card); chains move together only when you have the cell/column capacity to move them one at a time. No luck β pure planning.
Tableau: build downward, one rank lower each play. Chains that follow the rule move together. Empty columns accept anything.
Pull-backs: the top card of any stack can be pulled back down to a legal tableau spot β a real way out of trouble.
Stock: tap to deal one card. When empty, tap to redeal the waste β two redeals maximum.
Controls: tap to select (legal spots glow green), tap a destination to play, tap the selection again to auto-play β or just drag the cards.
Fair play: in Battle-Stack modes the table warns if a placement strands a rank, and warns when no winning line can be found. Undo is unlimited.
Same shuffle for every player, generated and solver-verified before publication.
