Well, the % system is usually 85% to 95% and is not random.
There are 3 types of calculating it:
- Partially
- Total
- Bonuses (Min 20000 - Max 100000)
Let we say is 85%... and we played 1000 coins...and the slot earned from you 10000
You must check if the partial is about the 85% of the played coins (850)
You must check if the total is about 85% of the total coins played (8500)
You must check if is the time for bonus, so if the slot earned too much to release the current bonus
For the bonus is easy, you make it choose the right symbol for the bonus.
For example if you have the lemon that gives 20000 and a melon that give 50000 and the bonus must give 40000 the machine will choose the lemon....
Another good random mode is the total random when over 85% of all and bonus is not ready.
In this way the machine will seem more random.
I will upload a video in some minutes so you can see how this machine work.
Long life to Steve!
