How it works

01 Β· INSERT

Drop your memecoins in

Insert bags you already hold β€” no SOL required. They become play credits and stock the prize pool.

02 Β· TURN

Crank the handle

A server-authoritative, provably-fair draw resolves a weighted outcome across 7 rarity tiers β€” with a pity ceiling and a progressive jackpot. The bubblegum machine even sounds off. πŸ”Š

03 Β· WIN

Keep it or cash out

Most turns land a bag; rare turns land legendaries. Hit Mythic for the whole jackpot + a bag of the featured freshly-launched token.

the math

7 tiers, probabilities sum to 1.0. Base EV β‰ˆ 0.885 β†’ house edge β‰ˆ 6.5%. Verified over 200,000 simulated pulls; pity never exceeds 50. The edge funds depositor yield (45%), $GACHA buyback & burn (30%), treasury (15%), reserve (10%).

provably fair Β· commit-reveal

Verify every pull

Before you play, the server commits to a secret serverSeed by publishing SHA256(serverSeed). Each pull's outcome = HMAC_SHA256(serverSeed, clientSeed:nonce:0) β†’ first 52 bits / 2^52. Rotate to reveal the seed, check the commit, then recompute any pull. No client-side RNG.

The $GACHA machine

Depositor yield

The house doesn't pocket the rake β€” it shares it. Everyone who fills the machine earns a share of every turn's fees, plus $GACHA emissions and yield on idle backing. Fill it, earn while your bags sit.

$GACHA β€” earn only by playing

Fixed supply, fair-launched on Emblem Launchpad. At genesis the only way to get it is to play. Every turn routes fees into the Furnace: 70% burned, 30% recycled to players.

Provable fairness

roll = HMAC_SHA256(serverSeed, clientSeed:nonce:0) β†’ first 52 bits / 2^52 ∈ [0,1) commit = SHA256(serverSeed) β€” published before play

Launchpad-into-gacha

Keyed by mint (Meteora DBC β†’ DAMM v2). New tokens load straight into the prize pool; the featured drop is a real launchpad token read live via launch_get. Full build docs: /gachameme-docs.
