A 50-sided die with the roulette's bets, based on a Dan Spevack's idea. Labels: 1, 2, 3, ..., 36, 0, 00, ODD, EVEN, HIGH, LOW, BLACK, RED, 1-12, 13-24, 25-36, Col 1, Col 2, Col 3. The circular dimples are all identical, placed in a symmetrical, quasi-regular pattern on the sphere.
I don't know how fair it is, in any case: "this is not intended to replace a roulette wheel. It is essentially a random number (bet) generator...a novelty item. A person takes the die with them to the table. So a lack of perfection in equality is not a dealbreaker. (Dan Spevack)"
DISCLAIMER. I got a WSF print of this die (see photos). That was a test version with flat dimples. Unfortunately it is somewhat disappointing due to the poor rendering of many tiny details. The enhanced version now available has concave dimples (see 3D and renderings) to ensure more stability. In any case I *strongly* recommend the frosted detail materials (which can also be easily painted with acrylics) instead of SF. I have uploaded also a larger version of the same die that is more suitable for the cheaper materials. Due to the many faces, this die should be rolled on a hard surface (wood, marble) to be sure that it lands clearly on the dimples.
