⛓ QUICK GUIDE
HOW TO PLAY
Mempool Survivors is a horde-survival arcade game on Bitcoin SV — you're a node fighting to stay online. Every block you survive becomes a real on-chain transaction.
Survive the horde. Move with WASD / arrows / drag. Weapons auto-fire. Grab the sats enemies drop to level up and pick upgrades.
Two ways to play.CASUAL — endless: survive as long as you can, ranked by time. RANKED — a daily 15-minute sprint ranked by score, no paid powerups. The “same daily seed” means everyone that day faces the exact same enemies, drops and layout (like a daily crossword) — so scores compare fairly. A fresh seed drops every day.
Play on-chain (recommended). In the menu, pick who pays under WHO PAYS FOR THIS RUN and tap the big orange PLAY button to fund your run — your wallet asks you to approve once, then every kill is a real 1-sat TXBLASTER transaction you sign (live rain on bsv.lol). You pay ONLY the miner fee — sats per kill . The leftover sats are swept back to you when you die.
WHAT DOES IT COST? 1 enemy = 1 real tx = sats — the raw miner fee, zero markup from us. A typical 1,000-kill run ≈ sats . You fund once; whatever you don't spend is swept back to your wallet automatically when you die. How we make money: optional extras only — premium powerups ( sats ), ship skins and the ranked pot — never required to play.
No wallet? Play free. The demo is on us — but limited to 2 minutes per run. Connect a wallet to play unlimited.
Premium powerups. In Casual, every level-up deals 3 free upgrades + 2 gold premium cards you can buy with your wallet — REORG, 51% STORM, MEMPOOL FREEZE, ASIC TURRET, DOUBLE-SPEND DECOY and more. Ranked has no paid powerups — pure skill.

Send BSV to this address. You pay only miner fees ( sats/kill); the rest returns to you when a run ends.

—
Send $BLASTER — or any 1Sat ordinal — here, from Yours, 1Sat or anywhere else. Tokens sent to the BSV address above will NOT show up in-game. Both addresses come from the same 12 words, so one backup covers both. Keep a few sats on the BSV address: spending tokens pays the miner fee from there.
BACKUP · your 12 words
These 12 words ARE your wallet and your name. Write them down offline. Anyone who has them controls your funds — and we can NOT recover them for you.
