Bonus Shop
The SpinBoss Bonus Shop converts loyalty coins earned through play into the rewards you actually want. Coins are awarded for deposits, wagering, completing daily challenges and finishing in tournament leaderboards. Inventory rotates weekly, expands as you climb the VIP programme, and currently includes:
- Free spins bundles (10, 25, 50, 100, 200 spins on rotating games)
- Free bet vouchers (£5, £10, £25, £50 sports stakes)
- Bonus cash (£10 to £250, wagered at 30x)
- Wager-free spins (Diamond VIPs only)
- Tournament tickets and event invites
Special tournaments & challenges
SpinBoss runs rotating slot races, network drops, weekly cash giveaways and themed challenges. Most challenges sit inside the Missions tab and reward coins or free spins on completion. Claiming and tracking offers works identically from your phone — see the mobile platform guide for setup. The Bonus Drop calendar around Christmas, Easter and major football tournaments adds limited-time offers on top of the standing menu.
General bonus rules
Before claiming any offer, it is worth setting limits via the responsible gambling tools so wagering progress stays inside your own budget.
All bonuses are subject to standard SpinBoss terms: one bonus active per player at any time, no bonus stacking, maximum bet of £5 per spin or £10 per hand on table games while a bonus is in play, bonus funds and winnings forfeit if maximum bet is exceeded or if the same game session detects irregular play. Wagering is calculated on the bonus amount only, not the full deposit + bonus. Bonus winnings beyond the bonus amount itself are paid out as real cash after wagering is cleared and processed through the same deposit and withdrawal methods you used to deposit.
