A simple game that tests your reflex and counting speed.
Your goal is to enter the sum shown on all dice. You have only 90 seconds.
In the first level you add up the 4-digit dice. After reaching a total of 1000 points you'll unlock the next level, with 5-digit dice. Then, 6 - and 7-digit.
Points are cumulative throughout the game.
For best results, train every day.
