At this high level of odds allowed, which is much greater than the norm, all put bets are better than the corresponding place or buy bets.
In the case of 20 times odds the house edge of the put bet on the 4 and 10 is 1.59%, on the 5 and 9 is 0.95%, and on the 6 and 8 is 0.43%. The effect is the same as making a place bet or buying odds, but the house edge is different depending on the multiple of odds allowed. While the player can make an odds bet immediately on top of the put bet, the opportunity to win on the initial roll is lost.
The player may choose the point to be established on the put bet.
For other readers, let me explain that a put bet is making a pass or come bet after a point has already been established.
