Four quick brain games, a few minutes a day. Each one is a race against an AI opponent, and every game has its own leaderboard. THE GAMES Math Rush: quick sums against the clock. Build a combo and every answer counts for more. Memory Flip: remember where the cards are, then find the pairs. The boards grow as you clear them. Reaction Tap: tap green, avoid red, and catch yellow for double points. Logic Grid: find the rule in a sequence, a grid or a set of numbers, and pick what comes next. Survival: waves of math, logic, memory and colour questions, faster each time. Three lives, and a power-up between waves. FAIR TO PLAY, FAIR TO COMPARE The puzzles are the same for everyone at each level, so a score means the same on every phone and in every language. Choose an easy, medium or hard opponent; harder ones give more XP. EVERY DAY - A daily challenge with a score to beat - Daily and all-time leaderboards for each game - An optional reminder at 6 pm with the day's challenge PROGRESS - XP, levels and ranks from Bronze to Diamond - Achievements for each game, quests and weekly challenges - Stats that show your strongest skill, your accuracy and when you play best CALM BY DESIGN A quiet dark interface with one thing to look at on each screen, sound and vibration you can turn off, and a Reduce motion setting.
