What Is a Gacha Simulator?
A gacha simulator is an online tool that recreates the thrill of capsule toy machines and mobile gacha games without any real-world cost. The word "gacha" comes from gachapon, the Japanese vending machines that dispense collectible toys in clear plastic capsules. In video games, the same mechanic powers huge titles like Genshin Impact, Fate/Grand Order, and Pokémon Trading Card Game Pocket — you spend currency, a random prize drops, and rarity determines how happy you feel. Our gacha simulator lets you define your own prize pool, assign weights and rarity tiers (common, rare, epic, legendary), and pull for free as many times as you want. It is perfect for practicing loot-table design, teaching probability, streaming pity-system content, or just scratching the gacha itch without opening your wallet.

How to Use the Gacha Simulator
Using the gacha simulator takes three quick steps:
- 1.Build your prize pool. Each row has a name, a weight (the chance out of the total), and a rarity tier — common (gray), rare (blue), epic (purple), or legendary (orange). Add up to 20 prizes with the + Add Prize button and remove any you do not want with the × button.
- 2.Tune the weights. By convention weights should add to 100, but any positive total works — if the sum is not 100 we show a small note and draw from the actual total anyway. A typical curve is 70 common, 25 rare, 5 legendary.
- 3.Pull. Click Pull Once for a single weighted draw, or Pull x10 for a ten-pull with the full pool still in play each time. The capsule card scales in with a 500ms reveal animation, rarity counters update, and your last ten pulls are kept in history.

Why Use Our Gacha Simulator
Our gacha simulator runs entirely in your browser with cryptographically secure randomness, so every draw is provably fair and nothing is logged on a server. Unlike a spreadsheet of percentages, you get a real capsule-reveal animation, rarity-coded cards, and running pull statistics — the same feedback loop that makes real gacha addictive, minus the microtransactions. Your prize pool saves automatically between visits, and the share link encodes the whole table so teammates, viewers, or students can play with your exact setup. Pair it with our Ichiban Kuji Simulator when you want draws without replacement, our Slot Machine Simulator for reel-matching luck, or our Winner Picker wheel for straight-up name drawing. Together they cover every randomness format you are likely to need for content, classrooms, or tabletop nights.
