KŌINI Dice
99 fair dice, true entropy
Free · Designed for iPad. Not verified for macOS.
99 fair dice in one press. Every roll is drawn live from your device's own cryptographic core — no servers, no network, no data collected. 6^99 possible outcomes.
KŌINI Dice is a beautifully simple, provably fair dice roller. Press once and it generates 99 individual six-sided dice rolls — instantly, right on your device.
Every roll is created the moment you press the button, using your iPhone's built-in cryptographic random number generator. Nothing is pre-computed, nothing is stored, and there is no pool of numbers to pick from. Each of the 99 results is generated from scratch, in real time.
TRUE ENTROPY
The randomness comes straight from your device's operating-system cryptographic core (SecRandomCopyBytes). It is never seeded, cached, or reused between presses.
EXACTLY FAIR
Each die face lands with a probability of exactly 1 in 6. KŌINI Dice uses precise byte-level sampling so no face is ever favored — fairness by construction, not by approximation.
COMPLETELY OFFLINE
The app never touches the network. It has no ads, no accounts, no analytics, and no tracking of any kind. It collects no data whatsoever.
WHAT YOU SEE

Whether you are gaming, teaching probability, settling a decision, or you simply love genuinely fair randomness, KŌINI Dice gives you 99 honest rolls every time — with 6^99 possible outcomes for a single press.
No sign-up. No ads. No data. Just fair dice.
