The Dice Multiplier allows you to spend more Dice Rolls on a single tap, multiplying the rewards you get from landing on a tile. For example, using a x5 multiplier and landing on a tile that gives 100 coins will grant you 500 coins instead. It also multiplies the points you earn for tournaments and the rewards from Invasion and Snatch mini-games, making it the fastest way to climb the ranks. Use it strategically when you feel lucky or are close to a goal!
