420

Players sit across from each other at an initially cleared table. The two players, Red and Blue, take turns maintaining a "hand" of four dice of their own color. 420 was designed by Mark Steere in September 2025. PLAY Starting with Red, players begin by rolling all four of their own dice, forming their hand. On each of your subsequent turns, you must reroll 1, 2, 3, or 4 of the dice in your hand, and add them back into your hand. OBJECT OF THE GAME The goal is for the dice in your hand to total exactly 20. No more, no less. For example, (6, 5, 5, 4) is a winning hand. It's possible to win the game on your first turn, with a probability of 2.7% - about 1 in 37 plays. REROLL RESTRICTIONS You can always reroll 4 dice. You can only reroll 3 dice if the remaining die has a value of at least 5. You can only reroll 2 dice if the remaining 2 dice sum to at least 10. You can only reroll 1 die if the remaining 3 dice sum to at least 15. GOING OVER AND RESET If your hand sums to 21 or higher, on your next turn you must reroll all four of your dice (reset). —description from the designer
