Campaign and controls
Tap Start Expedition and select an unlocked stage. The first-stage tutorial lets you try movement, rotation and drop. Clear rows to reach the stage target before the computer opponent. The campaign has 50 stages across eight sectors and works offline without an account. Stages 51–100 are planned and not playable. Clearing two, three or four normal rows sends one, two or four attack rows, before incoming attacks are cancelled. A single row sends no attack. Cleared gray attack rows do not count toward the stage target. The round Rotate button, smaller Swap button above it and separate Drop button are spaced apart. Pause offers Resume, Retry and stage selection.
Crystals, themes and races
In version 1.2.0, a first stage clear awards one crystal. Campaign Swap costs one crystal and can be used three times per battle. Clear Line is no longer available. Crystals also unlock permanent cosmetic board themes without changing game rules.
Optional bonus races show the reward rules before you choose to race or continue straight to the next stage. Five collected stars equal one crystal; finishing adds one, up to four crystals total. Use Switch Lane or tap the track to avoid obstacles. Skipping forfeits that race opportunity.
Recharge is beside the crystal balance. Choose Watch Ad to earn one crystal after completion. Up to three ad rewards are available per 24 hours across Recharge and races. New rewards stop at a balance of 100; older higher balances remain. Unavailable or unfinished ads grant no extra reward. In battle, Recharge pauses play; Resume Battle returns to the saved position. Crystals have no cash value and cannot be bought. Earlier app versions used different rewards and item rules.
Nearby VS
Choose Nearby VS on both devices, then host on one and join on the other. Keep devices nearby, enable Bluetooth and Wi-Fi and grant discovery permissions when prompted. On Android, confirm the same pairing code on both devices. A match continues until one player tops out; there is no target line count or Swap item.
Android requires compatible Android builds on both devices. iPhone and iPad use a separate Apple nearby connection system; the current Android and iOS versions do not support cross-play. There is no internet matchmaking or account login.
Music, ads and interruptions
Use the top music and haptics controls, with additional audio options in Settings & Support. Tracks rotate automatically. Announcer and haptic availability depend on the device; Android uses an installed offline English voice when available. Check device volume and connected audio outputs if sound is missing. Gameplay and audio pause when the app leaves the foreground.
Banners sit above the app content in version 1.2.0. Optional rewarded ads require an internet connection. The initial Android closed-test build uses Google test ads. No real-ad revenue is implied by that test build. Core gameplay remains available without an ad.
Saved progress and privacy
Progress, crystals, themes, combo records and settings are stored locally. Continue Battle resumes an unfinished campaign battle. There is no account or cloud synchronization. Clearing Android app storage or deleting the app removes local data; iOS offloading may preserve it. Support cannot restore lost saves.
