- The expanding wild reveal is the central mechanic — pray for a high-paying symbol (Osiris itself)

Treasures of Osiris — frequently asked questions
Treasures of Osiris is a Pragmatic Play video slot released in 2024. It runs on a 5x3 grid with 25 paylines, a published RTP of 96.16%, medium volatility and a maximum payout of 2,500x your bet. The core hook is an Egyptian-themed reel set with an expanding-wild free-spin bonus. What changes between sessions is variance — the 96.16% figure is a long-run average measured across millions of spins, not a per-session guarantee.
Treasures of Osiris publishes a return-to-player of 96.16%, which is in line with the 96% category average for online slots. That figure comes directly from Pragmatic Play's certified maths sheet and represents the long-run payback across millions of spins. On a single session the actual return can swing far above or below 96.16% because medium volatility spreads outcomes widely. Play with your head and treat the 96.16% as a lifetime average, not a session target.
Treasures of Osiris caps the maximum single-round payout at 2,500x your total bet. At a £1 stake that caps a single round at £2,500, and at £0.10 the cap works out to £250. That ceiling is a mathematical cap coded into the game, so once a round hits 2,500x it settles and stops paying — no further multipliers apply. Reaching the cap is genuinely rare: it happens rarely but it does happen, and the odds are in the region of once per hundreds of thousands of spins on medium volatility builds like this.
Sign in to Mr Punter Casino, deposit from £10 in GBP or crypto, and search "Treasures of Osiris" in the slot library. Pick a stake between £0.10 and £100 per spin, adjust auto-play if you want a fixed number of rounds, and press spin. Symbol combinations pay along the 25 paylines, and the Egyptian-themed reel set feature triggers when the on-screen conditions land. It happens rarely but it does happen, so pace your stakes accordingly.
Yes. Treasures of Osiris runs full-feature in the Mr Punter Casino progressive web app on iOS Safari and Android Chrome, and no native app install is required — you save it to the home screen and it launches like a standalone. Feature parity with desktop is complete: same 96.16% RTP, same 2,500x cap, same bonus mechanics. What changes is screen real estate — the paytable and stake selector collapse into tabs, but every button is thumb-reachable. A steady 4G or Wi-Fi connection is enough; the game weighs a few megabytes after the first load.
Yes. Treasures of Osiris is an RNG title, so it is available in free-play demo mode inside the Mr Punter Casino library — open the game tile and pick "Demo" or "Play for fun" before the real-money session starts. The demo runs on the same maths engine as the live version, so the expanding-wild feature during the free-spin round behaves identically. Demo balances reset when you refresh, and any wins in demo mode are pretend credits, not withdrawable cash. Live-dealer and some crash titles skip demo mode, but this one has it.
There are no tricks that beat a certified RNG. Treasures of Osiris uses a random number generator audited by Pragmatic Play's testing house, so past spins tell you nothing about the next one. What actually helps is bankroll discipline: budget for medium volatility with roughly 100x to 150x your base bet, set session stop-loss and stop-win limits, and treat the 96.16% RTP as a lifetime average. Chasing losses after a cold streak is where most players do the real damage. Play with your head and use the session limits inside Mr Punter Casino if you need them.
Treasures of Osiris is offered at Mr Punter Casino, which is operated by Mondero Enterprises Ltd under an Anjouan Gaming Board licence (ALSI-152406028-FI2) — not the UK Gambling Commission (UKGC). That means UK-specific consumer protections do not apply here: GamStop self-exclusion is not integrated, the ADR scheme for UKGC operators does not cover this site, and there is no mandatory affordability check under UKGC rules. You can access the site from the UK, but you are transacting with an offshore operator. Age 18+ only. For gambling support call GamCare on 0808 8020 133 (free, 24/7) or visit BeGambleAware.
Treasures of Osiris contributes 100% to the wagering requirement on the £500 Mr Punter Casino welcome bonus, which is the standard rate for the slot category. That means every £1 you stake on Treasures of Osiris counts as £1 of wagering progress. Bonus Buy purchases can contribute at a different rate — sometimes 0% — so if you use the Buy Feature check the active bonus terms first. Live-dealer titles, video poker and table games count at reduced rates. Always re-read the current T&Cs before starting wagering, as excluded titles rotate between campaigns.
Yes. Mr Punter Casino accepts Bitcoin, Ethereum, Litecoin, Dogecoin and USDT alongside GBP card payments, and you can play Treasures of Osiris with a crypto-funded balance the same way as with fiat. Deposits credit as soon as the network confirms — usually within 10 to 30 minutes depending on the chain — and there is no separate crypto lobby, the same game tile serves both funding types. Wagering contribution stays at 100% on crypto stakes, and the £500 welcome bonus works with a crypto deposit converted at the on-site GBP rate. Withdrawals settle back to the same wallet you deposited from.
