No turns — both players slam cards at once. Empty your five stacks before the computer empties its own.
This is the only card game here with no turns at all. You and the computer play simultaneously, and the round ends the instant one of you runs out of cards.
Each side starts with five stacks holding one, two, three, four and five cards. Only the top card of each stack is live. Tap one of your face-up cards to throw it onto either of the two piles in the middle. It is a legal throw when your card is exactly one rank above or below the pile's current top card, and the ace joins onto the king as well as onto the two. Suits are irrelevant.
When your card fits both piles, the game plays it for you onto the pile that is less useful to your remaining cards, so that the top you leave standing is one you can still reach later. Green outlines mark every card you can legally throw right now.
If a moment comes when neither side has a legal throw, two fresh cards are turned onto the centre after a short pause and the race restarts. Clear your stacks first to win the round; win rounds back to back to build a streak, and one loss sends it to zero.
Speed here is mostly a scanning problem, not a tapping problem. You have five tops and two piles, which is ten comparisons, and doing them one at a time is far too slow. Instead, hold the two pile ranks in your head and read your row of five looking only for those four target numbers — one above and one below each pile. That turns ten comparisons into a single sweep.
Spend your big stacks first when you have a free choice. The tall five-card stack only reveals one new card per throw, so if you leave it until the end you will be sitting on a pile of cards with just one live top while your opponent still has five live tops to work with. Throwing from your longest stack keeps your options wide, which matters far more than shaving a card off a short one.
The empty stack is the trap most people miss. Once a stack is gone it stays gone, so a stack you cleared early is one fewer chance to have a matching card later. Late in a round the player with three live tops loses almost every stalemate to the player with five, even if they are behind on total cards.
When you are stuck, do not stare at the middle waiting — look at your row and pre-decide which card you will throw for each of the likely new pile tops. The refresh comes fast, and the player who has already decided gets one or two free throws before the other has finished reading the new cards. That head start is usually the whole margin in a round this short.
