I may be missing something here, but is there a better way to change your bet than hitting left and right? I've tried the R1/2 L1/2 buttons and up and down, and even holding down left and right, but the only controls that seem to work are to tap left and right once for every 100 you want to change the bet. This gets incredibly tedious when you're trying to raise 5000. (50 taps? Ridiculous.)
If they don't have a better way to increase your bet faster, then I really hope they patch in a better control scheme than this.
