In snooker you have to first pot a red ball. Then you can choose which colour (non-red) to pot. If a player misses a red or a colour then play switches to the other player.
The red-colour combination continues until all of the reds have been potted. Then the colours need to be potted in order from yellow to black.
In mathematical snooker you pot a ball by multiplying the running total by a number from 2 to 9 to get an answer that has the value of the ball as its left hand digit.
For example if the running total is 6, you can multiply by 2 (2x6=12), or 3 (3x6=18) to pot a red. Assume you used 3 and have a total of 18 then you should choose green (2x18=36), blue (3 x 18=54) or black (4x18=72).
However there is a limitation; you cannot use either of the last two numbers that you have used to multiply. So in the example above you would not be able to use 3.
If you do use one of the last two numbers, or use a number lower than 2 or higher than 9, or try to use a number that is not a whole number then that is a foul shot.
If you make a foul shot then your opponent gets 4 points (5 if trying for the blue, 6 if trying for the pink, or 7 if trying for the black) and play changes to your opponent.
When only the colours remain then you are allowed to multiply by numbers from 2 to 14.
