Secure the bottom positions
The target card shows the final four discs in every track from top to bottom. Preserve discs already correct near the bottom whenever possible.
Slide full rows and columns to match four-color target cards across 120 progressive levels, a daily puzzle, sound, and account-free friend challenges.
Route the top disc of each track through the transfer lane and into another column to match the target card.
Level 64 / 120
Tap the top disc of one track, then tap its destination track—or drag it sideways. Each track holds up to six discs.
The target card shows the final four discs in every track from top to bottom. Preserve discs already correct near the bottom whenever possible.
Each track holds six discs while the target uses four. Park blocking discs in a track with free capacity, then uncover the color you need.
Only the top disc of a track can enter the transfer rail. Compare the four available discs before choosing a temporary storage track.
Hard puzzles may reduce the match count while you uncover a buried color. Plan the final four-layer order instead of chasing the current score alone.
Select the top disc of one track and route it through the upper transfer lane into another track. You win when all four tracks contain four discs in the order shown on the target card.
The target uses four discs per track, while two extra positions provide working space. To reach a buried color, temporarily move the discs above it into tracks with spare capacity.
Yes. Drag the top disc of a track toward its destination, or tap that disc and then tap another track. The same pointer controls work with a computer mouse.
There are 120 levels across Starter, Explorer, Challenge, and Master stages. Scramble depth rises gradually, and every board starts from legal reversible track moves.
The current date produces a fixed level and board, so everyone receives the same puzzle that day. It changes automatically the next day and requires no account.
No. After winning, Invite Challenge opens the header share panel with a URL carrying the level, board seed, moves, and time. A friend can replay the exact puzzle anonymously.
Only the uncovered top disc in each track can enter the transfer lane. A destination holding six discs is full, so move one out before routing another disc into it.
Secure the required bottom colors and reserve one track as temporary storage. Uncover buried colors first, then rebuild each track in target order to avoid repeated transfers.
It develops color classification, visual pattern recognition, spatial transformation, working memory, and multi-step planning, making it suitable for children’s logic practice.
