🪙 HotelFlip

Two hotels. One price.
Flip for the upgrade.

Name your ideal hotel and a backup. Pay the exact midpoint in Monero. A future Monero block — unpredictable, public, verifiable — decides which one you get. Win the flip and you stay luxury at a discount. Lose it and you still stay, just at the backup.

When block is mined, its hash decides: last hex digit even → ideal hotel, odd → backup hotel. This page checks automatically.

Draw block

The rule was published before the draw block existed. The hash was unknowable until miners found the block. Neither you nor the operator could influence it.

Why it's provably fair

🔮 Unpredictable

Monero block hashes can't be known or chosen before the block is mined.

📜 Committed early

Your draw block height is fixed the moment payment verifies — before that block exists.

🔍 Publicly checkable

Look up the block hash on any Monero explorer and apply the even/odd rule yourself.

HotelFlip is a pricing game, not a lottery: you always get a real hotel stay. Chance-based pricing rules vary by jurisdiction — check local regulations before operating with real payments.
