Gakuran Roll Simulator
Simulate full Gakuran rerolls for free with this gakuran roll simulator — every roll uses the official developer-published odds for style rarity, ethnicity, face tiers, and hair dye, and tracks what all those rolls would have cost in Robux.
Official published odds — free to roll, no Robux spent
Character Gender
Pick a gender and hit Roll to simulate a full Gakuran reroll with the official odds.
Every tier rate here is the official developer-published number. The specific style or face inside a tier is drawn uniformly — the developers haven't published per-option splits, so treat within-tier picks as an assumption.

How The Gakuran Roll Simulator Works
In Gakuran, a single reroll re-randomizes your whole character at once — fighting style, ethnicity, height, last name, face, hair, and accessories — at about 2 Robux per spin. This gakuran roll simulator recreates that spin using only the rates the developers have actually published: the five style rarity tiers (??? 0.075%, Legendary 1%, Epic 10%, Uncommon 30%, Common 59%), the official ethnicity odds (Japanese 95%, all five others 1% each), the face rarity tiers from the reworked face system, and the 5% hair dye event with its ultra-rare Pastel Pink and White chances.
Where the developers publish only a tier rate, the simulator rolls the tier at its real odds and then picks uniformly inside it — for example, a Legendary style roll is a genuine 1-in-100 event, but whether it lands on Kure, Capoeira, Wrestling, Hakari is an even split because no per-style breakdown has ever been published. The same honesty rule covers what the simulator won't fake: height rolls on a continuous scale where only per-ethnicity averages are official, natural hair colors have no published per-color odds, and the surname you'd get is one of 6,064 names in ethnicity-specific pools the developers haven't released. The simulator reports those as pools and averages instead of inventing exact values.
Rare Pulls Worth Chasing
The headline chase is now the "???" tier at just 0.075% — currently Ali, the rarest style pull in the game — with Legendary styles (Kure, Capoeira, Wrestling, Hakari) next at 1%, about 1 in 100 rolls or roughly 200 Robux of real rerolls on average. The reworked face system added rare pulls of its own: the Mogger tier sits at 1% with nine named variants per gender, the Neko cat faces at 2%, the female-only Gyaru tier at 5%, and the Secret Faces at just 0.1% — gender-split, so each face is exclusive to one gender though any ethnicity can roll it. Rarest of all are the special hair dyes: Pastel Pink at 0.0015% and White at 0.0005%, odds so long you may never see one even in thousands of simulated rolls.
Use the ×10 and ×100 buttons to get a feel for how streaky real rerolling is — the session tally tracks your rarity counts, notable pulls, and the Robux you'd have burned in-game. If you'd rather see the expected cost of hunting a specific target instead of spinning for it, the Roll Calculator computes expected rerolls and Robux for any style-and-ethnicity combination, and active codes from the Codes Wiki can fund free rerolls to chase these odds in the real game.
How To Use The Roll Simulator
Pick Your Character's Gender
Gender changes the face-tier odds: the Gyaru tier (5%) is female-only, the Secret Faces (0.1%) have separate male and female sets, and the Regular pool differs slightly (62% male / 57% female). Pick the one you play.
Roll — Once Or In Bulk
Hit Roll for a single spin, or ×10 / ×100 to batch-roll. Each simulated roll draws style rarity, ethnicity, face tier, and hair at the official published odds, exactly one full reroll's worth of randomness.
Read Your Pulls And Session Stats
The latest-roll card shows each factor with its real probability, and the session panel tracks totals by rarity, your notable pulls, and what the session would have cost in Robux at ~2 Robux per reroll.
Roll Simulator FAQ
Is this gakuran roll simulator using the real odds?
Yes — every tier rate is the official developer-published number: style rarities (??? 0.075%, Legendary 1%, Epic 10%, Uncommon 30%, Common 59%), ethnicity odds (Japanese 95%, others 1% each), face tiers, and the 5% hair dye event. The only assumption is inside a tier: no per-style or per-face split is published, so the simulator picks uniformly and says so.
Does the simulator cost Robux or affect my real character?
No. It's a free fan tool that runs entirely in your browser — nothing connects to Roblox or your account. In the real game a reroll costs about 2 Robux; the session stats show what your simulated rolls would have cost so you can budget before spending.
What's the rarest thing I can roll in the simulator?
White hair dye, at an official 0.0005% (Pastel Pink is 0.0015%). Among styles, the "???" tier (Ali) is rarest at 0.075%; among faces, the Secret Faces are rarest at 0.1%, gender-split into male and female sets that any ethnicity can roll.
Why doesn't the simulator show an exact height or surname?
Because the developers haven't published that data. Height rolls on a continuous scale with only per-ethnicity averages official, and the 6,064 rollable surnames are ethnicity-specific pools whose actual name lists aren't public — so the simulator reports the official average and the pool size instead of making values up.
How many rolls does it take to get a Legendary style?
At the official 1% tier rate you'd expect about 100 rolls on average — roughly 200 Robux in-game — but streaks in both directions are normal, which is exactly what the ×100 button demonstrates. Whether a Legendary lands on Kure, Capoeira, Wrestling, Hakari isn't published, so the simulator splits the tier evenly.
What's the difference between the simulator and the roll calculator?
The simulator experiences the odds — it spins full random characters so you can feel how rare pulls actually land. The Roll Calculator computes them — expected rerolls and Robux cost for a specific target style and ethnicity. Use the calculator to budget and the simulator to scratch the reroll itch for free.
Can I get free rerolls in the real game?
Yes — active Gakuran codes regularly reward free rerolls (15, 10, or 5 depending on the code). Check the Codes Wiki on this site for the current hand-verified list before spending Robux.
