When doing this always click the number 0 so it highted you can click before and make it 10,,20,30 etc.
Ok I love me some sudoko with in the first few puzzles had all the medels except where you had to solve so many and ones from each group.
I like the game but 40 random boards gets repetive for most.
Flaws with the timing mechanic
What no medal for 30 solved?
