Your instincts are WRONG. That's the whole game. Opposite Day! flips everything you know about reaction games. The screen says TAP — so you don't. It says DON'T TAP — so you do. Simple to understand, hilariously hard to actually do. HOW IT WORKS • Read the instruction • Do the EXACT OPPOSITE • Do it fast — hesitate and you lose a heart Tap, hold, and swipe your way through levels that get faster, trickier, and sneakier. Just when you think you've rewired your brain, the game flips the rules again. WHY YOU'LL LOVE IT (AND HATE IT) • One-hand, one-minute rounds — perfect for queues, commutes, and "one more try" spirals • Levels that escalate from "easy" to "how did I fail THAT" • 3 hearts per run — every mistake counts • TODAY'S TRICK — a fresh daily challenge to keep your brain on its toes • Clean, hand-drawn notebook style with zero clutter TRAIN YOUR BRAIN BY BREAKING IT Opposite Day! isn't just about speed — it's about impulse control. Suppressing your first reaction and doing the reverse is a genuine mental workout. You'll feel your brain fighting you. That's the point. Easy to learn. Impossible to master. Infuriatingly fun. Think backwards. React smarter. Play Opposite Day! Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
