The puzzle game
A 3×3 sliding tile puzzle. 60 seconds. One QR code to reassemble.
Each puzzle is a QR code image sliced into a 3×3 grid. Eight tiles can be moved; one slot is empty. Slide tiles into the correct order before the timer runs out.
Game rules
Tiles can only slide into the empty adjacent slot — up, down, left, right, no diagonals.
The puzzle is solved when all tiles are in the correct order.
Winning within the time limit earns a $SCAN prize based on your current level.
Failing to solve before the timer expires uses the attempt with no reward.
Every puzzle played on a token with an active Scan Mode campaign contributes to its progress, regardless of outcome.
How a puzzle session works
A player opens a puzzle for a token.
A QR puzzle is generated.
One play is consumed from the active pack for that token.
The player solves before the timer ends — or the attempt expires.
The result is recorded and rewards, progression, and analytics update.
A session can end as a win, loss, timeout, or invalid. All outcomes are recorded and affect player history, leveling, and campaign eligibility checks.
Where to play
QRbase is available as a Farcaster mini app and a Web app at qrbase.xyz. The QR image embedded in each puzzle is styled with a randomly selected listed partner's token logo.
