This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own Arm Wrestle Simulator session. It will not click the shop.

Drop probability

At least one hatch

Estimates the chance of seeing a pet at least once if every egg is an independent roll. The default 1% is the published Frog chance on the School Earth egg, not a universal rate. Replace it with the percent printed for the pet you want. Luck boosts, multi-hatch purchases, and pity are not included. Eggs whose listed chances do not add to 100% are a bad fit for this model.

Listed hatch chance (%)Eggs opened

Enter values from your session.

Chance of at least one success = 1 − (1 − chance per attempt) raised to the number of attempts.

Default chance is the published Earth egg Frog rate of 1%. Type the rate from the egg you are actually opening.

FAQ

Arm Wrestle Simulator calculator questions

How do I leave the School?

Defeat Champion and hold 15,000 Wins. The Escape School door next to the bosses is the published exit into the Gym.

What does Rebirth reset?

The August 17, 2026 guide says a normal Rebirth spends Wins, sets Bicep, Hand, and Knuckle strength to 0, and keeps Trails plus your remaining Wins. Super Rebirth also resets Trails, Wins, and worlds, keeps Arms, and gives tokens worth +100% Total Strength each while you hold them. Another rebirth listing describes a flat +15% per rebirth and a different keep list, so confirm the button text.

Where do I enter a code?

Look for a Codes button on the side of the screen, or open Store and use the Codes control, then press Verify. Each code is once per account. Lists published October 1 and October 2, 2026 disagree about harborking, so that string is not marked active or expired here.

How many worlds are there?

The official experience listing says 28 worlds. A published world index names 19 normal worlds, and only School through Space Center have exit numbers here. The official listing says 28 worlds, so later names are missing.
