Tap Up/Down: the higher-or-lower game on a provably fair market.
One decision. Higher or lower.
The simplest Tap title: will the index finish higher or lower than its start price when the round expires? Odds are locked the moment the stake is accepted, and the round runs on the same provably fair engine as Tap Markets™: a synthetic market path generated from a committed seed, with a fixed, published RTP.
The loop.
Pick a side
Higher or lower than the index price at the moment the round starts. Two buttons, zero learning curve.
Lock the odds
The payout is fixed the instant the stake is accepted, so the player knows the exact return before the round starts.
Expiry settles
When the window closes, the round's generated path answers. Ties void and refund under the published rules.
One decision, provably fair.
- The entry game. The shortest path from lobby to first round: one decision every player already understands.
- Synthetic RNG, not a price feed. The path is generated from a committed seed; reference feeds anchor only its look and pace. No exchange hours, no feed outages, no market exposure for the operator.
- RTP comes from the paytable. Fixed and published, from probability and payout, never from the feed.
- Published tie rules. Finish exactly on the start price and the round voids and refunds, defined in the rulebook, not decided by support.

Player disclosure: Tap Up/Down is a casino game of chance. The price path is generated by a provably fair RNG and does not show live market prices; playing does not involve buying or owning any asset.
