SpinCastle Casino Bonus Maths: £5,000 + 550 Spins
Our welcome package is split across your first four deposits. Each stage has its own code, its own percentage and its own cap, and each can be used once. The table puts two numbers side by side: what a £20 deposit earns, and the deposit that reaches the stage's ceiling.
| Stage and code | A £20 deposit gets you | Deposit that fills the cap |
|---|---|---|
| CASTLE1, 400% up to £2,000 | £80 bonus + 200 spins on Starburst | £500 |
| CASTLE2, 200% up to £1,000 | £40 bonus + 150 spins on Hook's Heroes | £500 |
| CASTLE3, 150% up to £1,000 | £30 bonus + 100 spins on Magic Portals | about £667 |
| CASTLE4, 100% up to £1,000 | £20 bonus + 100 spins on Gonzo's Quest | £1,000 |
Where the value sits
The first stage gives the most per pound. At 400%, every £1 you deposit adds £4 of bonus until £500 has gone in. The fourth stage returns £1 for every £1, so its appeal lies in the size of the cap rather than the rate.
Two ways to take the package
At the minimum, four £20 deposits cost £80 and bring £170 in bonus money plus all 550 spins. That gives you £250 to play with before a single spin has paid. At the top end, deposits of roughly £2,667 unlock the full £5,000, or about £7,667 across the four stages. Pick the stage where your usual deposit fits, not a cap you would never otherwise spend.
