Goal

Tap the numbers in order — 1, 2, 3… — as fast as you can. Each number you tap is replaced by the one 25 higher, so the grid always holds the next 25. How far can you count in 60 seconds?

Scoring

Every 25 numbers is a level. Each tap is worth 4 + the level. A wrong tap costs 3 points and briefly locks the grid — so look, don't mash. Get 10 in a row to build a streak.

Tips

• Glance ahead: while you tap one number, look for the next.
• Use a smooth sweeping eye movement rather than hunting number by number.
• Numbers you just replaced are the highest on the grid — you can ignore them for a while.

Visual Scanning Speed

Finding numbers in a cluttered field trains your eyes to sweep and lock onto targets faster — a skill that transfers to reading, driving, and everyday search tasks.

Focused Attention

Keeping the count while ignoring the other numbers exercises selective attention — staying on task without getting distracted.
