Brain Infinity vs 明鏡

Math, logic, memory, attention and language in about three minutes. 10-question sessions, 30 levels, 3,000 English and 3,000 Japanese questions, with a brain companion. ■ Reasoning challenges 900 four-choice puzzles in 15 formats across 5 areas. Runs of 10 at Easy, Standard or Hard clear with 5, 7 or 9 correct; 45–120 seconds per question. See guides, clues and explanations, with diagrams for some puzzles. Resume anytime. ■ Training and Action Lab Normal runs mix 7 focus, 2 review and 1 stretch questions, with fewer repeats. Hints give clues; review explains why. Up to two reports per run; offline reports retry later. Action Lab has 10 hands-on formats: numbers, patterns, memory, attention and words. Play 10 untimed puzzles at three difficulties. Progress and bests are saved. Starting and resuming attempts is free. ■ Training builds a colony Build seven colonies, each with six facilities up to Lv.10, using Lumina and Core levels from training. Open rooms, follow flagged goals and meet the crew. Restore 36 areas per colony for journals and the next colony. Command three companies, capture generators and reclaim the core within four minutes. Upgrades strengthen your side; area difficulty is fixed. Practice is free. Expeditions restore equipment without Lumina or XP. ■ Records and community Infinity ends after three mistakes or timeouts. Composite anomaly starts with 45 seconds, extended by correct answers. Rankings show this week, last week and all-time records. You join automatically; your name and new records are public. Opt out in Settings. The Community feed shares your name, bests, streak milestones and main missions. Celebrate milestones. Sharing starts on; turn on Opt out of sharing achievements in Settings to stop new posts. Published posts remain. Sharing, rankings and analytics have separate controls. No free-text posts, images or chat. ■ Review and daily goals The notebook keeps 200 misses from all modes. Filter by category and retry up to 10 pending questions for double Lumina and Core XP per answer. Reviewed entries are read-only. Normal training and challenge runs award 1 Lumina and 10 Brain Core XP per answer, right or wrong; skips, unanswered timeouts and reports do not. Daily missions cover training, reasoning and Action Lab. Finish all three for a calendar mark. Track medals, streaks and all 30 levels. Research Lab shows your Brain Core and Neural Index, an in-game indicator, not a medical or intelligence assessment. Normal questions allow 30 seconds, including time away from the app. A silver medal (80%) unlocks the next level. Bronze 60%, silver 80%, gold 100%. ■ Optional accounts and cloud saves Play without linking an account; progress stays on your device. Link Google or Apple in Settings to save progress, your name and birth year privately in the cloud and restore on another device with the same account. Birth year is not public. If both saves changed, choose one; XP and items are not combined. Purchases and ad/analytics consent are not transferred. Unlink or request account deletion in Settings. Deletion starts removing public data and holds the last cloud save and app account for 30 days before permanent deletion. Cancel with the original account during that period to restore the last cloud save. Public data and unsynced changes are not restored. ■ Display, ads and data VoiceOver, large text, high contrast, reduced motion, effect captions and three music tracks. Set reminders and sound in Settings. A banner appears at the end of Lab. A full-screen ad may appear before results, at most once per five completed runs, never while answering. The optional one-time Remove ads purchase hides both, with no renewal. Every puzzle plays without it; restore with the same store account. Questions work offline. Purchases, ads, rankings, feed, cloud/accounts, reports and analytics need a connection. Analytics runs after the age check while sharing is on; stop it in Settings. See the Privacy Policy.
