This is a 7 numbers bet.
Consider these groups of 9 numbers:
RED HIGH
RED LOW
BLACK HIGH
BLACK LOW
TRIGGER- Note from the history of spins the last group hit. Remember that number. Now spin until that sleeper awaken and hits again, (a different number hit in that particular group). Now, bet all numbers in that group except those 2 numbers.
For an example number 3 (RED LOW) was the last group hit, now you spin until number 14 hits (RED LOW). Now all numbers are bet in RED LOW except 3,14. (7 numbers bet)
Progression- Double bets after a cycle of 5 spins.
Recovery: if not a new high is reached, go down one step in the progression line (1 2 4 8 16...) for an example you win at step 4 (8u), now the next bet, for the next trigger would be 4u, if not reach a new high, next bet is 2u...and so on
Optional: -if you reach 1u in the recovery line, and still not reached a new high begin at 2u until recovered.
