2/3 is a very popular betting system with high winning odds. The basic principle of this betting system is based on the probability theory. You will be able to use this betting system only in those online casinos where you are allowed to skip a spin, not to bet. NetEnt casinos are the best for this purpose.
The principle of this betting strategy is not complicated. At roulette, there are 37 sections with corresponding numbers: 36 single numbers and one zero. In this betting strategy, 1 round is 37 spins of the roulette wheel. Statistics say that in one round, no more than 2/3 of all numbers win (24 numbers from 37 on the roulette wheel). Some numbers win more than 1 time.
The player needs patience, a pen and a sheet of paper to record the winning numbers. The player records the winning numbers for 28 spins, and on the 26, 27 and 28 spin of the roulette wheel, there must be at least 1 repeat of the winning number. If there are no repetitions on the last three spins, then we wait for the next round and start again.
The total number of winning numbers must not exceed 21 (that is, 3 less than 2/3 of 37 sections). If the number of recorded numbers is more than 21, this means that in the next spins there will be repetitions from those numbers that previously won. In this situation, we are also waiting for the next round.
How to Bet?
If all the conditions described above are met and in 28 spins only 21 numbers win, then at the 29-th spin, we enter the game and bet on the system. We bet on those numbers that have not won yet. Out of 37 numbers, we choose 16 numbers that are not on our list. We bet on a straight number and the group of its neighbors. If we place a chip per number, then we spend 16 chips, but if one of these numbers wins then the payouts will be 35:1.
The 2/3 betting strategy is a kind of complement to the methodology "We are waiting for the third time", which is based on statistics, that if a number wins in a round 2 times, then it will definitely win for the third time. That is, the player marks the number that won the second time and bets on it until it wins for the third time. If several numbers have won the second time, then the player bets on each.
That is, your records are useful for the betting system "We are waiting for the third time" and for the 2/3 betting systems. And if the first betting system does not bring the desired result, then with the second betting system you will return the lost money at least.
