split the wheel into six sections PIEs (see pic)
Trigger: bet the opposite six numbers of the wheel (PIE) than the current pie hit.
Each trigger is valid only for 3 spins, then bet a new trigger for 3 spins.
these are the "PIE-pairs"
1-4
2-5
3-6
pie 1 hits, bet pie 4.
pie 5 hit, bet pie 2
...and so on
