Spit is what happens when a card game deletes the concept of turns. You and your opponent play simultaneously, firing cards from your stockpiles onto two shared center piles the moment a legal move exists — one rank higher or one rank lower than the pile's top card, suits ignored, with the rank order looping so ace sits between king and 2. Nothing stands between you and your next play except how fast you spot it, because the other side is scanning the same two piles at the same time.
Every round opens from the same split. Each side takes 26 cards, fans 15 of them into five stockpiles stacked one through five cards deep, and keeps the remaining 11 in reserve as a spit pile. Clear your five stockpiles before the AI clears its own and the game is yours on the spot — one round is one game here, with a fresh 26-card split every time you hit Play Again. If the board deadlocks with nothing left to spit, the win goes to whichever side holds fewer cards.
If you learned Speed and wonder how Spit differs, the short answer is the layout: Spit deals your cards into solitaire-style stockpiles, while Speed plays from a simple hand and draw pile. The Speed guide on this site walks through that game's setup and rules in full, including exactly where Spit and Speed differ.
The AI's pace is a setting, not a mystery. On Slow it fires a move roughly every second and a half — enough breathing room to think between plays. Normal tightens the gap to about 0.8 seconds, and Fast plays at a ruthless 0.3, with a couple hundred milliseconds of random jitter layered onto every level so its rhythm never becomes something you can simply memorize. You can change the speed mid-game and it takes effect immediately.
Deadlocks have a built-in escape hatch. When no visible card on your side connects to either center pile, hit the Stuck button; once both players are frozen, fresh cards flip onto the center piles and the race reignites. The app checks your board before it lets you bail — the Stuck button stays disabled while any of your cards is still highlighted as playable.
