Twilight Grids is a dual-grid logic puzzle game where every puzzle has one solution — and no guessing. Each puzzle splits into a day grid and a night grid that share clues but follow their own rules. Reading them together is the whole game. No timer, no ads mid-puzzle, no pay-to-win. Just clean deduction. CAMPAIGN Seven unlock chains teach you one mechanic at a time — row parity, island counts, light runs, split gradients, tornado constraints, twilight tiles, and snake paths. Once you've cleared them, branch into mixed 12-level chains that combine everything you've learned. Stars roll up into badges, chain tiers, and a titles ladder from Wanderer to Twilight Eternal. RACES Span races kick in mid-campaign, pacing four opponents against your progress. Active play keeps them on your tail; take a long break and they'll catch up. Finish first for badge rewards. PERKS Earn badges to unlock three perks. Extra Mistake adds buffer lives to every puzzle. Streak Saver protects a missed daily. Badge Bonus stacks on top of every completion, growing with your total badge count. ACHIEVEMENTS Twenty-plus achievements, from easy daily-streak milestones to hidden skill feats. Clean Run rewards a 12-level chain solved without a single mistake or hint. First of Many celebrates your first Infinity Mastery cycle. Twilight Sage caps the progression at 200 total badges earned. INFINITY MASTERY After you clear a GL's mastery demos, its grid sizes open for endless free play. Each cycle completes when you've earned enough 3-star solves at that size, awarding badges and pushing toward the 10x10 Master achievement. DAILY PUZZLE One new daily puzzle per day, rotating across all seven GLs. Streaks track your consistency; Streak Saver catches a missed day. QUICK PLAY Random puzzles from the full pool, plus a favorites picker for your preferred GLs and sizes. CLOUD SYNC Optional Game Center sync preserves progress across reinstalls and devices. Every chain, badge, perk, and race record backs up. PLAY ANYWHERE Puzzles generate on-device and play fully offline once installed. Optional Game Center sync keeps progress across reinstalls and devices. INFINITE PUZZLES Beyond the campaign, every grid size in Infinity Mastery has its own endless cycle of procedurally-generated puzzles. Solve as many as you want at your own pace — each cycle awards badges and pushes you toward the 10x10 Master achievement. ADS AND IAP One optional interstitial ad appears periodically between non-daily puzzle completions, with Infinity subscription available to remove it if you prefer ad-free play. Rewarded ads unlock optional hints; the daily puzzle is always ad-free in the play flow. DESIGNED FOR DEDUCTION Every puzzle is machine-verified to have exactly one solution. If you think you're stuck, you're not guessing right — the path is there. Built for solo players who enjoy sitting with a problem until it cracks.
