Offer more intuitive multipliers

[Liongrass]

Currently Sats Dice only let's people choose between the following multipliers: 1.5, 2.5, 3.5, etc up until 19.5. I find these highly counter-intuitive, and would prefer easy multipliers such as "double", "triple" or "quadriple". Telling people "double your sats" is so far more appealing than "2.5 times your sats back".
