Get every digit right. Normal is two digits in 4 tries. Medium is three digits and Hard is four or more, each in 5 tries.
Every puzzle hides a true piece of good news. Solve it faster for more points: 10x on the first try, less on each try after. Medium pays double and Hard pays triple.
Three puzzles count each day: today's Normal, Medium and Hard. Practice rounds after that are just for fun.
