How scoring works

Every game on Noggin is marked out of 100, so a day adds up to one number. Here is how this one earns it.

Component	Effect
Solved on the first check	90
Solved on the second	80
Solved on the third	70
Finished in under 7 minutes	+10
Took more than 12 minutes	−10
Each hint taken	−8
Out of checks	Up to 25, for the cells you had right

A perfect Deduce — first check, no hints, inside seven minutes — is exactly 100. A careful eleven-minute solve is 90.

The clock only counts when you solve it. There is no reward for failing quickly, and a slowness penalty on top of a failure would be unkind.

The clock stops while you are reading this.

The same for every game, including streaks and how the day is totalled.
