How the game works

The board is dealt full. Tap a piece and it pops onto the top of your stack, and the cell it left is refilled at once — so the board is a source rather than a space. The top three pieces of the stack clear when each attribute — colour, number, shape and, at Deep, the arrow — is either all-same or all-different. Nothing lower down the stack is ever tested.

The See what clears screen inside the game is an editable lab: change any piece and it tells you live whether the line clears and why. It is the fastest way to learn the rule.

Common questions

• My stack is full. That is how a run ends — but not while you can still get out of it. Lift the top piece aside into the hold spot and keep popping underneath it, or sweep the stack clean with ⌫. You get three sweeps a run.
• I paid and it is asking me to pay again. It should not: Stackit is bought once, up front, and there is nothing inside it to buy. If a store is asking twice, write to us with the receipt and we will sort it out with them.
• Clearing data lost my records. Clear data wipes settings, records and today’s streak on that device, and it cannot be undone. The game itself is untouched, and so is your purchase — that belongs to your store account.
• The daily is the same for everyone? Yes — one seed a day worldwide, rolling over at midnight UTC, played on the same board at the same length, with the same allowance of help. One attempt each, so the day compares play rather than who replayed it most.

Refunds

Purchases are handled by Apple and Google, so refunds go through them: reportaproblem.apple.com or Google Play’s order history. We cannot issue them on their behalf, but tell us what went wrong anyway — that is how it gets fixed.
