How to Play

🎯 Objective

Answer brain challenges before the timer runs out. Complete all challenges in a level to earn points and stars, then unlock the next level!

❤️ Lives

  • You start each game with 3 lives.
  • A life is lost when you answer incorrectly or the timer runs out.
  • Lose all lives and the round ends immediately.
  • Lives refill automatically — 1 life every 15 minutes, up to a max of 5.
  • Watch a short ad to instantly earn an extra life at any time.

⏱️ Timer

Every challenge has a countdown timer shown as a ring. Answer before it hits zero or you lose a life. Higher levels have shorter timers!

🟦 Plenty of time
🟨 Hurry up!
🟥 Almost out!

🏆 Scoring

  • Correct answer = 100 points
  • Fast answer (under 1 second) = +50 bonus
  • Perfect round (zero mistakes) = +500 bonus
  • Score is multiplied by your active combo tier

🔥 Combo Multiplier

Chain correct answers together to build a combo and multiply your points!

0–1 streak×1
2–3 streak×2
4–6 streak×3
7–9 streak×5
10+ streak×10 🔥

One wrong answer or timeout resets your combo to zero.

⭐ Stars & Ratings

  • 1 Star — Score 600+ points
  • ⭐⭐ 2 Stars — Score 1,200+ points
  • ⭐⭐⭐ 3 Stars — Score 2,000+ points

🗺️ Levels

Mind Blink has 30 levels. Each level gets faster and introduces more challenge types. Earn enough total points to unlock the next level — or watch an ad to unlock locked levels!

📅 Daily Bonus & Streak

  • Return every day to claim your Daily Bonus of 100 × your streak days.
  • The longer your daily streak, the bigger the reward.
  • Missing a day resets your streak to 1.

🧩 Challenge Types

🌈
Color Test (Stroop Effect)
A color name is shown in a different ink color. Tap the correct ink color, not the word itself. Don't let your brain trick you!
🔢
Math
Solve an arithmetic equation (addition, subtraction, multiplication or division) and pick the correct answer before time runs out.
🔗
Chain Memory
A sequence of numbers is shown. Memorize them, then tap them in the same order from a shuffled grid.
🟦
Pattern Grid
A pattern of highlighted tiles flashes on a grid. Memorize it, then recreate the same pattern after it disappears.
🔤
Word Scramble
Letters of a word are scrambled. Pick the correctly unscrambled word from the options provided.
⚖️
Comparison
Two values or expressions are shown side by side. Decide if the left is Greater, Equal, or Less than the right.
Reaction
A grid of shapes appears. Tap the target shape with the specified color as fast as possible!
🔍
Odd One Out
A grid of colored tiles is shown. Find and tap the one tile that has a slightly different color from all the others.

💡 Tips

  • For the Stroop Test, focus on the ink color, not the word.
  • For Chain Memory, say the numbers out loud or in your head.
  • For Pattern Grid, group the tiles into clusters to remember them faster.
  • Build a high combo on easy challenges to maximize your score on harder ones.
  • Come back daily — streak bonuses stack up fast!
