Split Second - Count

How many dots did you just see?

Green dots flash on a gray board for a split second, then get covered by stripes. Pick how many there were from four choices. It is far too quick to count one by one, so this Chalna Series game trains your eye to take in a number at a glance.

At a glance

Players: 1 (take turns to compare scores)
Ages: 6+
Play time: About 1–3 min per game
Levels · Modes: One mode (3 lives; 3–5 dots at level 1, up to 16; visible time starts at 0.8s and drops by 0.05s per level, down to 0.3s; gray decoy dots from level 6)

How to play

Tap Start. After 3, 2, 1, green dots appear. Look carefully while the bar shrinks.
When the dots are covered, pick the number of dots from the four choices below.
After you answer, the cover lifts and each green dot gets a number so you can check.
Get it right to level up; get it wrong and you lose a life. The game ends when all 3 lives are gone.

Tips

Don't count one by one — see them in groups of two or three. "Three, three, two makes eight" is much faster.
From level 6, gray dots join in. Sort by color first, then count only the green ones.
If you are unsure, trust your first impression rather than picking the middle choice.

Good to know

People can tell up to about four items at a glance without counting. Psychologists call this "subitizing". Beyond that, grouping helps. The puzzles are new every time you play.
