The Pools — Stake £20, Get 100 Free Spins on Big Bass Splash

Complete Step-by-Step Guide

How to Complete This Offer

1. Register at The Pools
   Create a new account at thepools.com. You automatically opt into the casino welcome offer upon registration — no separate opt-in is needed, but you should visit the Games Promotions Page and click the Welcome Offer banner to confirm your participation. The Pools is operated by The Football Pools Limited, licensed by the UK Gambling Commission.
2. Deposit £20 via Debit Card
   Deposit at least £20 within 7 days of registration. Debit card is required — PayPal, virtual cards, pre-paid debit cards and certain other payment methods will not qualify for this offer. Deposits below £20 will not count toward the qualifying requirement.
3. Stake £20 on King Kong Cash
   Wager your £20 on any eligible casino slot. A good option is King Kong Cash by Blueprint Gaming at 95.79% RTP — keeping your expected qualifying loss to around £0.84. The qualifying stake must be on casino slots only. Complete this within 7 days of opening your account.
4. Open Big Bass Splash and Accept Your Free Spins
   Once your £20 qualifying stake is complete, your 100 free spins will be automatically credited — allow up to 5 minutes. Open Big Bass Splash from the slots lobby and accept the in-game pop-up to activate your spins. If the spins don't appear, try logging out and back in before contacting customer support. Play all 100 spins at 10p each — any winnings go directly to your cash balance.
5. Withdraw Your Winnings
   Once all 100 spins are complete, head to the cashier and withdraw your free spin winnings alongside any remaining balance from your qualifying stake. There are no wagering requirements on free spin winnings — everything is withdrawable immediately.

Understanding the Expected Value

Here's how the £8.83 EV breaks down:

Free spins EV: 100 spins × £0.10 × 96.71% RTP (Big Bass Splash) = £9.67 expected return

Qualifying wager loss: £20 on King Kong Cash at 95.79% RTP = −£0.84 expected loss

Total EV: £8.83 expected profit

Note that this offer requires a £20 deposit and qualifying stake — double that of most offers on this site. The higher qualifying cost accounts for this in the EV calculation. The free spin value itself (£9.67 expected) is one of the strongest on the site due to the 100 × 10p combination.
