HAHU rules:
1. once you start the game, the main timer (30 seconds) will start for you to solve as many puzzles as possible
2. for each puzzle you will be given a random set of 4 cards, each with a numerical value
note: A = 1, J = 10, Q = 10, and K = 10
3. by using ALL of 4 values, think of a way to produce 24 or 40 with basic math operations in 3 steps
example: 5, 6, J, K
step one: J : 5 = 2
step two: 6 - 2 = 4
step three: K x 4 = 40
4. if you think you have a solution, press 'HAHU!', the main timer will pause for 15 seconds, and the HAHU timer (in red) will start for you to do your calculations
5. if you succeed, you get the remaining time in the HAHU timer as your points
6. if you fail, you lose 15 points
7. you can sacrifice 1 point to skip any puzzle
have fun!
