What You Get
Deposit £20 and wager £20 each day on Age of Gods: God of Storms to unlock that day's spins. GRP Casino credits you with 40 free spins on Big Bass Splash (at 10p each) once you've placed the qualifying wager for that day. Repeat daily for 5 consecutive days to collect all 200 spins.
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 200 free spins, minus the expected cost of the five daily qualifying wagers on Age of Gods: God of Storms.
| Component | Calculation | Value |
|---|---|---|
| 200 free spins at £0.10 | 200 × £0.10 × 96.65% | +£19.33 |
| 5 daily wager costs | 5 × £20 × (100% − 96.14%) | −£3.86 |
| Total EV | ~£15.47 |
£15.47 is the mathematical expectation across many completions. The five daily wagers cost around £3.86 in expected losses, with the bulk of the value coming from the 200 free spins. RTPs used: Big Bass Splash 96.65% (Pragmatic Play), Age of Gods: God of Storms 96.14% (Playtech).

-
Deposit £20Make a deposit of at least £20 using an eligible payment method. Keep your balance above £20 across all 5 days, as you'll need to wager £20 each day to unlock that day's spins. Topping up between days is fine if needed.
-
Each day: wager £20 on Age of Gods: God of Storms to unlock 40 spinsLog in each day and navigate to Age of Gods: God of Storms (by Playtech). Place a £20 wager to unlock that day's 40 free spins on Big Bass Splash. The expected cost of each £20 wager is just £0.77, so across all 5 days you're risking around £3.86 in expected losses on the qualifying bets. Repeat for each of the 5 consecutive days.

Tips for This Offer
- Set a daily reminder for all 5 days. You need to log in, place the qualifying £20 wager, and use the 40 spins each day. Missing a day means missing 40 spins.
- Keep an eye on your balance. You need at least £20 available each morning before wagering. If your balance dips below that from the previous day's wager, top up before continuing.
- Place the full £20 on Age of Gods: God of Storms in one bet each day rather than splitting it across smaller bets. Keeps it clean and straightforward.
- Big Bass Splash is a medium-to-high variance slot. Your results from 40 spins will swing day to day. Over all 200 spins, the numbers 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 variance swings heavily in your favour.
