Launch: toss the cow
Our Yeti winds up and hurls the HashCashCow across the snow. Bet whether she lands OVER or UNDER your line. The line is a multiplier, so you see the payout before you toss. Every landing is provably fair and the game returns 98% to players.
How to play
- Pick OVER or UNDER.
- Choose a line, from 1.01x up to 100x. Each 1x is 10 metres.
- Set your bet in play credits and tap Toss the cow.
- On OVER bets, cash out mid-flight or let her fly.
Provably fair
Landing = HMAC-SHA256(server seed, client seed:nonce). Learn the method in our provably fair guide or check a hash with the hash verifier.
Launch FAQ
Is Launch free to play?
Yes. Launch uses play credits only. You start with 1,000 credits and can refill any time, so no deposit, signup or real crypto is involved.
What is the house edge in Launch?
The house edge is 2%, so the return to player is 98% on every bet. Each payout is 0.98 divided by the chance of winning, which is why a 2x line pays 1.96x and a 3x line pays 2.94x.
How do I know the toss is not rigged?
Before each toss you see a SHA-256 hash of the server seed. The landing comes from HMAC-SHA256 of that seed, your client seed and the round number. Rotate seeds to reveal the server seed and check any round in the verify box.
When can I cash out?
On OVER bets you can cash out while the cow is still flying, at 98% of the live multiplier. Once the cow starts to land, cash-out locks so nobody can use the landing to beat the odds.
