How rolling and luck work
Roll to Defend is a roll-based tower defense game where you spin for random units and send your best pulls out to fight endless zombie waves. Every roll draws a unit whose rarity is written as odds — a common 1 in 10K near the start, climbing all the way to a 1 in 10B secret at the top of the ladder. Rarer units hit harder, so the whole loop is a chase for better odds: roll units, equip and place them on the path, clear the waves for Coins, then pour those Coins straight back into more rolls.
Luck is the lever that bends the odds in your favor. Raising your Luck stat shifts every future roll toward the deep end of the ladder, turning a one-in-a-billion daydream into something you might actually hit. You gain Luck for free by liking the game, joining the developer group for the EXTRA LUCK bonus, and playing alongside friends, and you can stack more through the Permanent Luck and VIP gamepasses. Coins keep piling up even while you are offline, so a strong field left defending overnight funds a fresh burst of rolls the next time you log in.
New to the game? The beginner guide walks the first hour step by step, the rarity and odds page breaks down every rung of the ladder, and the codes page tracks whether Roll to Defend has any active codes yet. This Roll to Defend Wiki keeps each system — rolling, luck, zones and waves, and gamepasses — documented with the game's real numbers rather than guesses.
