TrackQ: Focus Training
Card shuffle chasing puzzle
Free · Designed for iPad. Not verified for macOS.
Keep your eyes on the marked card. Everything else is a lie. Don't trust your eyes.
Some cards are marked. Then everything goes face down and the shuffle begins. Can your eyes keep up?
TrackQ is a card-tracking puzzle built on the classic shell game. Watch where the marked cards start, follow them through a shuffle designed to lose you, then tap the slots where they landed. No luck. No guessing. Just your attention against the board.
HOW TO PLAY
- The marked cards are revealed for a moment
- Every card flips face down
- The board shuffles as cards swap, swarm and jump
- The timer starts only once the shuffle stops
- Tap every slot holding a marked card
400 STAGES
Start on a gentle 3x3 grid and work your way up to a 7x7 board packed with 49 cards. Grids grow, shuffles lengthen, and the number of cards you have to hold in your head climbs with them. Every stage is tuned on its own, so the wall you hit is always the next one.
THE SHUFFLE FIGHTS BACK
This is not a simple swap. Cards move in groups, several at a time, and the shuffle plants deliberate bluffs:
- Feints that look like a move but land right back in place
- Marked cards hiding inside a crowd of movers
- Twin jumps that pull your attention in two directions
You will lose a card. The real question is whether you can find it again.
CHALLENGE MODES
Three fixed single rounds, each with its own personality:
- Speed Run - one card, a 7x7 board, and a blistering shuffle
- Swarm - two cards at once at a steady, readable pace, free to cross the entire board
- Chaos - two cards through the longest shuffle in the game, and the hardest round on offer
Four mistakes allowed. Clear a run and the points stack onto your running total.
