Play the campaign
Tap Start, then an unlocked stage. Drop a light into a column and connect four horizontally, vertically or diagonally before the computer. Win to unlock the next stage. You can retry without a limit or replay completed stages.
There are 50 playable stages in five sectors. A boss guards each tenth stage. Stages 51–100 and VS Mode are marked Coming Soon and are not part of the current playable release.
The campaign and computer opponent work on your device without an account or internet connection.
Bonus races and undo
A random bonus race appears once in each five-stage group, after the introductory stages. Read the How to Play guide and try a lane switch before your first run. The clock stays stopped until you press Start Race. Tap the screen or Switch Lanes to move between two lanes. Avoid barriers and survive 20 seconds to earn one bonus undo. A collision ends the race but does not remove campaign progress. Stars are a local score with no cash value.
After a race ends, you can also choose to watch a rewarded ad once for one additional bonus undo. Closing the ad without earning its reward does not grant an undo. A bonus undo is saved on your device and can be used without an ad in a later match. With no bonus undo available, you can choose to watch a rewarded ad for one undo, up to two ad undos per match. An undo rewinds your last move and the computer reply. It is available on your turn, before a match has ended.
If an ad is unavailable or you close it without earning a reward, your board and remaining allowance stay unchanged. Keep playing, retry later or restart the stage. No purchase is required.
Interstitial ads may appear when you restart a stage or retry after an AI defeat. The first two minutes of each app session are free of interstitials, and interstitials are spaced at least three minutes after the last full-screen ad. An unavailable ad is skipped immediately. The banner appears above the game. Full-screen ads do not interrupt a move or bonus race.
Music and accessibility
Use Music On/Off on the main menu or during a game. The left and right arrows change between three original music tracks. Settings includes sound effects and reduced motion. If sound is missing, check Silent Mode, your device volume and connected audio devices.
Music pauses when the app leaves the foreground. A race also pauses when interrupted. The game uses a portrait layout and provides labeled column buttons.
Progress and privacy
Completed stages, the current board, bonus undos, stars and settings are stored on your device. Use Resume Stage on the title screen to return to an unfinished match. Starting another stage replaces the current board. There is no account or cloud synchronization.
Deleting the app removes its local data. On iOS, offloading may preserve data. On Android, clearing app storage also removes saved progress. Support cannot remotely recover a lost save.
