Roll any even-sided die. If the result is an even number, read it as 2. If the result is an odd number, read it as 1.
Roll a D6. If the die shows > 3, simply check the face down side for your result or use the following conversion: 4 is 3, 5 is 2, 6 is 1.
Roll a D6. If the result is an even number, read it as 6. Otherwise read it as 0. Roll another D6 and add this result to the first result.
Roll a D10 and multiply the result by 10. Reroll the die and add the second result to the first result. Any result of 10 on the D10 should be read as 0.
