2. 2Enter the codeType YUMMY35S into the bonus code field before you deposit.
3. 3Make the depositDeposit at least 20; the terms give this figure without a currency.
4. 4Check the bonus landsConfirm the 420% bonus and the 300 free spins are attached to your balance.
5. 5Read the rules firstOpen the bonus terms and check the max bet of 5 before you play.

The deciding terms are the 40x wagering, the max bet of 5 during play, and the 20 minimum deposit. The terms do not list a maximum cashout or an expiry date. The offer is listed as valid for Gates Of Olympus, so check that your play fits that game.

• Max bet during wagering is 5, so higher stakes play is restricted.
• Ask support to confirm any cashout ceiling before you deposit.
• The terms do not list an expiry date.
• The terms do not say whether 40x applies to the deposit, the bonus or both.
• Game restrictions and weighting: The terms do not give a weighting for other games, so check the bonus terms for which titles count toward the 40x.
• Country restrictions: Availability varies by location; the casino's terms list the excluded countries.
• Withdrawal limits: The terms do not list a maximum cashout for this bonus. The casino's payout window is 0-2 days, and crypto and e-wallets are the fastest routes.
• Excluded payment methods: Deposit methods include Bitcoin, BP Wallet, Dogecoin, Ethereum, eZeewallet, Flexepin, Interac, Litecoin, Mastercard, MiFinity, Neosurf, Tether, Tron and Visa. Check the bonus terms for which of these qualify for the welcome offer.

The wagering requirement is 40x. The terms do not say whether that applies to the deposit, the bonus or both, so I cannot price the playthrough for you. The sheet gives the multiplier and the minimum deposit as bare numbers, without the currency of those amounts and without the base of the multiplier, so no worked example is possible. What I can say is that 40x sits above the 30x I see on most welcome offers. Until the base is clear, treat the requirement as open-ended and ask support to confirm it in writing before you deposit.

I would take this if I plan to play Gates Of Olympus at stakes of 5 or less and I am comfortable with 40x wagering. I would skip it if I want to bet higher, because the max bet caps your play, or if I need a stated cashout ceiling before I start. The missing base for the multiplier is my main worry: without it, the playthrough could be far larger than the headline suggests. Ask support to confirm the base in writing. Play within your budget, and remember 18+.
