Find your flow. Break their orbit. Astral Falling Block Puzzle is a falling-block puzzle battle through 50 stages of a space expedition. Move and rotate pieces, clear full rows and reach your line target before an on-device AI opponent. A single cleared row defends without attacking. Double, triple and four-row clears create one, two and four attack rows. Incoming rows are canceled first, reducing outgoing attacks. - 50 campaign stages with gradually increasing challenge - Nearby survival battles between two Apple devices, with no line target - Three block swaps per campaign battle, costing one crystal each - Compact combo and attack alerts that keep your playfield visible - Spoken attack announcements, urgent incoming warning sounds and optional haptics - Original electronic music that changes automatically during play - Optional two-lane bonus races: five stars earn one crystal, with one more for finishing, up to four total - Permanent board themes unlocked with earned crystals - Campaign progress and unfinished battles saved on your device Choose whether to play each bonus race or skip its reward and continue to the next stage. Gray attack rows can be cleared, but do not count toward the line target or generate attacks. The campaign works offline without an account. Nearby VS uses local wireless discovery; both devices need the app, Bluetooth and Wi-Fi enabled, and local-network permission. Nearby battles do not spend or award crystals and contain no items. Optional completed rewarded ads grant one crystal, up to three ad rewards per rolling 24 hours. A post-race ad can be claimed once per eligible race and shares this limit. Earning stops at 100 crystals. Existing balances above that are kept. Banner ads occupy a separate area away from controls. Ads require internet and may not always be available. No in-app purchases or subscriptions. Game interface: English. Progress is stored locally; deleting the app may remove it. Stages 51-100 are planned and are not playable in this version.
