Reaction Grid is a minimal reflex game built around one simple rule: tap the active square as fast as you can.
Sounds easy—until the grid speeds up, your combo starts climbing, and a single wrong tap wipes your streak. How it works * A 5×5 grid appears on screen. * One tile lights up—tap it before time runs out. * The faster you react, the higher your score. Score like a pro * Speed Bonus: faster taps earn extra points. * Combo System: chain fast hits to boost your multiplier. * Penalties: tap the wrong tile and you lose points (and your combo). Game Modes * Classic (3 Lives): survive as long as possible while the tempo keeps increasing. * 60-Second Challenge: one minute, maximum focus—go for your best run. Climb the ranks * Track your best scores and push for the top of the leaderboard. Make it yours * Unlock and choose different Grid Themes (background + grid style variations) to match your vibe. If you enjoy games that are simple to learn, hard to master, Reaction Grid is your next “one more run” obsession.
