Project Soul's Calculator — Code Rewards & Reroll Odds
Editorial contact: Raymond
Total the Gems and Trait Rerolls your account can claim from the active codes, then model how far a trait reroll budget goes when the pool is unknown. Both panels use the inputs you enter and show their formulas.
Which code rewards can your account claim?
Enter your level, Reset count and whether the account owns an old gamepass. The totals use only the rewards published by the dated trackers; 7SOULS has no public breakdown and adds nothing.
| Code | Gems | Rerolls | Status |
|---|---|---|---|
| RESET | 100 | 5 | Needs Reset 1 |
| 2KCCU | 250 | 10 | Needs Reset 1 |
| 7SOULS | — | — | Eligible |
| BETA | 100 | 3 | Eligible |
| SUB2NOCTYRA | 50 | 5 | Needs Level 10 |
| OLDSOULS | 2260 | 47 | Needs an old gamepass |
| 250KVISITS | 100 | 5 | Needs Level 50 |
Still locked: 2,760 Gems and 72 Trait Rerolls. That is the value of the current level and Reset gaps, not a reason to skip them.
When to open the Project Soul's calculator
Before a code session
Enter the account level and Reset count to see which entries still refuse a redeem, instead of pasting every code and guessing why four of them failed.
Before a reroll spree
With an unknown trait pool, the useful number is the downside: how many rerolls a 90% chance needs at the rate you assume, and what a miss streak costs.
Before a Reset decision
350 Gems and 15 Trait Rerolls are waiting behind Reset 1. Compare that with the rest of the claimable pool before you trade a build for it.
How to read the Project Soul's calculator results
The code total is arithmetic on the published reward lines. If a tracker wrote "up to" for OLDSOULS, the planner uses the stated maximum and the table shows the same number, so the summary and the source cannot drift apart.
The odds panel is a model, not a data feed. Read the 90% column before the headline chance, and compare it with the rerolls you hold after visiting the codes page. If the budget only covers the 50% column, you are flipping a coin, not planning an upgrade.
The math inside the tools
Claimable total: each active code is tested against its published level, Reset and gamepass requirement, then its Gem and Trait Reroll values are summed. Locked rows are reported separately rather than silently dropped.
At-least-one odds: 1 − (1 − p)^n, where p is the chance you enter and n is the reroll budget. It assumes every attempt is independent and the chance never changes.
Attempts for a confidence level: the formula is inverted to find how many attempts reach 50% and 90%. A 5% chance needs 14 attempts for 50% and 45 for 90%, which is why a small reroll stock feels so swingy.
What it cannot do: it cannot tell you which trait is best, because no per-trait values exist to rank. Use the traits guide to judge a roll with your own clear-time test.
FAQ
What does the Project Soul's calculator do?
It has two jobs. The code planner adds up the Gems and Trait Rerolls an account can actually claim from the active codes, based on its level, Reset count and old gamepasses. The odds panel turns a target chance and a reroll budget into the probability of at least one hit, plus the number of attempts needed for a 50% and 90% chance.
Does it know the real Project Soul's trait rates?
No, because those rates are not published. The odds panel is a model driven by the chance you enter. Set the range you think is plausible, then look at the 90% column before spending a reroll stock you cannot replace.
Why does the code planner show fewer rewards than my level suggests?
The gates are independent. Level 10 unlocks SUB2NOCTYRA, Level 50 unlocks 250KVISITS, and Reset 1 unlocks RESET and 2KCCU regardless of level. If a reset is missing, those two codes stay locked. OLDSOULS also needs an old gamepass, and 7SOULS publishes no reward breakdown, so it adds nothing to the total.
Is the calculator free?
Yes. It runs in the browser, needs no account and sends no game data anywhere. The inputs stay on the page.
