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)"
Larger version, 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.
