Casinodays & Book of Oz UK 2026 — Live Casino

Tony C. · 2024-07-06T11:34:02+00:00

Casinodays casino review with Book of Oz (96.5% RTP) — UK community thread on 1 Spanish Company. 35x wagering, UKGC licensed.

Good question, been wondering this myself. The bit that catches most people out is when it comes to Casinodays and Book of Oz.

Sticky bonuses where you cannot withdraw the bonus amount itself are generally worse than cash bonuses even with a lower headline figure.

RTP is the return to player percentage over millions of spins. In any individual session it means almost nothing.

EV check on Casinodays welcome bonus: With 35x wagering on a £100 bonus, you need to stake £3500. At a 4% house edge that costs £40 to complete. Expected value: £40. Negative EV — treat as entertainment cost, not profit opportunity.

Key stats: Casinodays — founded 2020, 2,500 games, withdrawals typically within 3 hours. Book of Oz — Microgaming, 96.5% RTP, high variance.

If a casino is asking for documents before you can withdraw that is standard KYC not a scam. Upload them early to avoid delays.

Worth pointing out that on Book of Oz by Microgaming — RTP is 96.5% which is solid and it runs high variance meaning long dry spells broken by significant wins. Worth knowing before you spin. Feel free to ask if you need more info.

Been following this forum for a while and this one caught my eye. Quick maths on a £100 bonus here: with 35x wagering the expected cost is £0 in house edge losses before you see any real cash. The expected value on most casino bonuses is negative once you apply the house edge across the wagering requirement. That does not make them worthless but be realistic. Feel free to ask if you need more info.

Worth pointing out that on Casinodays since 2020. high wagering on their welcome offer. Massive 2500 game library with modern clean platform. Worth knowing: Newer brand with less proven withdrawal track record. Feel free to ask if you need more info.

NetEnt classics like Starburst and Gonzo still attract players despite their age. Starburst has 96.1% RTP which is fine for low volatility play.

Worth pointing out that — if you are playing Book of Oz with a bonus at Casinodays, check the game contribution table first. Most casinos count slots at 100% but always worth confirming. Feel free to ask if you need more info.

Been following this forum for a while and this one caught my eye. Always verify a casino holds a UKGC licence before depositing. Check the licence number on the Gambling Commission website directly.

On Book of Oz specifically — 96.5% RTP and high volatility. That means long dry spells broken by significant wins. Plan your session budget accordingly. Feel free to ask if you need more info.

Worth pointing out that. Casinodays has been operating since 2020 and their withdrawal time is typically 3 hour(s) via e-wallet for verified accounts. That is high wagering. Feel free to ask if you need more info.

Been following this forum for a while and this one caught my eye. From my experience with Casinodays: Massive 2500 game library with modern clean platform. The main negative is Newer brand with less proven withdrawal track record. Overall a decent option for UK players in 2026. Feel free to ask if you need more info.
