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.

Verdict
The clearest difference is rating: Mentraxia at 5.0 against Differences's 4.6. Mentraxia also leads on update cadence (every 4 days vs every 3 weeks). Differences's advantage is ratings volume (601K vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
