About Tumblin' Dice, from BoardGameGeek:

Tumblin' Dice is a dexterity dice game in which players take turns sliding, rolling, or flicking one of their dice down stepped surface. After all players have launched their four dice, they score points, multiplying the value of the die roll by 1×, 2×, 3×, or 4× depending on which area of the board the die has landed. (Dice which land in the 0× region are immediately removed from play.) After four rounds, the player with the most points win. Tumblin' Dice Jr. is a "travel" version of this game. Note that the player count of Tumblin' Dice has varied across multiple editions, with some sets having only four colors of dice and others having up to six colors. In addition, some sets have a -1x scoring area in place of or preceding 0x.
