Play the campaign
Tap Start Expedition and select an unlocked stage. Move and rotate falling blocks, clear full rows and reach the line target before your computer opponent. The round 90° Rotate button sits above the separate Drop button, with a gap between them. Clear rows to send attacks or cancel incoming attacks. There are 50 stages across eight sectors. Completed stages can be replayed without a limit. The campaign works offline without an account. Consecutive block placements that clear rows build a combo; a placement with no clear resets the streak. Your best combo is stored locally. Stages 51–100 are coming soon and are not playable yet.
Crystals and bonus races
A first stage clear awards one crystal. Spend one crystal to use Clear Line or Swap. Clear Line removes the lowest row containing locked blocks and lowers the rows above it, up to three times per battle. This item does not add target-line credit or send an attack. If the falling block prevents a safe clear, move it and try again; no crystal is spent. Swap can be used up to five times per battle. Its remaining uses are saved with an unfinished battle and reset for each new battle. Optional 20-second bonus races appear during the campaign: use Switch Lane directly below the track, or tap the track, to avoid barriers and collect crystals. Pause Race is beside the race title. Collected crystals are kept if you collide; finishing adds two. Skipping a race consumes that opportunity. Crystals have no cash value.
Tap Recharge beside the crystal balance on stage selection or in battle, then choose Watch Ad to earn three crystals after completing a rewarded ad. The stage-selection balance and Recharge button remain visible when scrolling. Opening Recharge in battle pauses both fields; choose Resume Battle when ready. No reward is added if the ad is unavailable or not completed. In version 1.1.0, after a bonus race with a positive reward, choose Watch Ad · +3 Crystals for three extra crystals once, regardless of the race score (subject to the balance limit). Earlier versions offered a doubled race reward. Your original race reward is saved immediately and remains yours if you skip or do not complete the ad. No purchase is required.
Version 1.1.0 adds banner ads in a separate area: above battles and bonus races, and below stage selection and battle results. Banners do not cover the board or controls. Ads need an internet connection and may not always be available; core gameplay remains available offline.
Music and interruptions
Use the music button to toggle audio and the arrows to change tracks. Settings & Support includes separate sound-effects, haptics and announcer controls. The optional on-device English announcer calls out large clears and combos; music is lowered during speech. Haptics depend on device support. If sound is missing, check Silent Mode, volume and connected audio devices. Gameplay and music pause when the app leaves the foreground.
Progress and privacy
Campaign progress, crystals, race opportunities, combo records and settings are stored on your device. An unfinished battle is saved locally and can be continued from the title screen. There is no account or cloud synchronization. Deleting the app removes local data; offloading may preserve it. Support cannot recover a lost save.
