Reckon you're good with numbers? Dots Connect Number is sure to prove you wrong - and will frustrate the heck out of you in the process.
The idea is to look at the image of numbers made from dots and guess what the number is, within the allotted time. You can take a hint which reveals one of the digits in the number, but it's still much, much harder than you'd think.
Dots Connect Number is very basic and the nag screens get annoying. But if you like a challenge you'll certainly find one here.
