SpinGrande Casino 100% up to €500 Deposit Bonus

SpinGrande Casino runs a 100% deposit bonus up to €500 for existing players. The code is VAULT3 and the minimum deposit is €100.

Bonus funds carry a 40xB wagering requirement and play on slots only. The offer closes on 2026-10-18. The weekend schedule is fixed: Saturday 00:01 to Sunday 23:59 UTC.

A deposit of at least €100 between Monday and Friday opens 20 free spins on Saturday and 20 more on Sunday. Both sets work on Heist Bank Rush. Spins aren't added automatically; they must be claimed by hand in the Rewards section of The Lounge on the matching day, no later than 23:59 UTC.

Each vault code works once per weekend, per player. That's the main limit to plan around. The structure suits players who already deposit during the week and want a weekend top-up rather than a one-off sign-up deal.
