Gacha Summon Simulator

Gacha Summon Simulator

Simulate rarity pulls

A gacha summon simulator models random pulls across rarity tiers. It is useful for understanding probability, testing reward presentation, or creating a playful reveal without real purchases.

Set the rates, pull, and compare results over multiple attempts. A rare result can appear early or late because randomness does not guarantee even spacing in a small sample.

This tool is for entertainment and probability learning. It does not connect to any real game, currency, account, or paid reward system.
