What You Get
Deposit and wager £20 once on Age of Gods: God of Storms to qualify. GRP Casino will then credit you with 200 free spins on Big Bass Splash at 10p per spin — but not all at once. Spins are delivered in batches of 40 per day over 5 consecutive days.
Free spin winnings are capped at £250. Given the expected value is around £19, this cap is unlikely to affect most completions — but be aware of it if variance goes heavily in your favour.
Expected Value Breakdown
This offer has two components: the expected return from the free spins, minus the small expected cost of wagering your deposit on Age of Gods: God of Storms.

Tips for This Offer
- Set a reminder for each of the 5 days so you don't forget to log in and use your daily spins before they expire.
- Wager the full £20 on Age of Gods: God of Storms in one bet rather than spreading it across multiple smaller bets — keeps it clean and simple.
- Big Bass Splash is a medium-to-high variance slot. Your actual results from 40 spins per day will vary — some days will pay more, some less. Over all 200 spins, results should trend towards the expected value.
- The £250 cap on free spin winnings is very unlikely to be hit at these stakes, but worth knowing if you're on a big run.
