Intro

Bison Casino offers a 100% welcome up to €500 with up to 100 free spins on Trout’s Treasure – Wild Rivers, plus up to 100 weekly free spins, at 30x and 20x wagering, under a Curaçao Gaming Authority licence.

Bison Casino is one of the more transparent options of its type: it names the free-spin slots, discloses the per-spin value, and runs lower wagering than most rivals.

The 100% welcome up to €500 adds up to 100 spins on a named slot, and a weekly offer repeats up to 100 more. It holds a Curaçao Gaming Authority licence.

Not a No Deposit Offer

Bison Casino does not offer free spins without a deposit, and there is no welcome no-deposit bonus. Both offers require a deposit, from €10. Neither needs a bonus code — the welcome is selected on the deposit page, and the weekly spins credit automatically with a qualifying deposit.

Welcome Bonus: 100% up to €500 plus up to 100 Free Spins

New players who deposit at least €10 receive a 100% match up to €500. The free spins are tiered by the first deposit and credited on Trout’s Treasure – Wild Rivers: deposit €10–99 for 10 spins, €100–199 for 50 spins (10 per day over 5 days), or €200 or more for 100 spins (10 per day over 10 days).

The match clears at 30x deposit-plus-bonus — the requirement is on the combination, not the bonus alone — and free-spin winnings clear at 30x as well, within 7 days. The spins carry a disclosed value of €0.20 each and are valid for 3 days. The maximum win that can be moved to the real-money balance from each daily batch of spins is capped at €150.

Weekly Free Spins: up to 100 Free Spins Each Week

The weekly offer credits free spins on a qualifying deposit with no code, tiered by amount: deposit €10–16 for 30 spins, €16–30 for 50 spins, or more than €30 for 100 spins. The eligible slot rotates each week among named titles — 3 Energy Diamonds: Hold And Win, 3 Gods Unleashed: Hold And Win, or Mole In The Hole.

These spins carry a disclosed value of €0.10 each, clear at just 20x — lower than the welcome — and are valid for 3 days. The maximum bet while the bonus is active is €2.

Spin-Value Matrix

Unlike most casinos of this type, Bison discloses the per-spin value, so the figures below are stated rather than estimated. The welcome spins are worth €0.20 each; the weekly spins, €0.10.

Offer (deposit tier)	Free Spins	Spin Value	Total FS Value	Source
Welcome (€200+)	100	€0.20	€20.00	Disclosed
Welcome (€100–199)	50	€0.20	€10.00	Disclosed
Welcome (€10–99)	10	€0.20	€2.00	Disclosed
Weekly (€30+)	100	€0.10	€10.00	Disclosed
Weekly (€16–30)	50	€0.10	€5.00	Disclosed
Weekly (€10–16)	30	€0.10	€3.00	Disclosed

Terms Worth Knowing

Neither offer needs a bonus code. The welcome is picked on the deposit page before you deposit; the weekly spins credit automatically with a qualifying deposit.
The maximum bet while a bonus is active is €2 — lower than many rivals — and that limit includes gambling features inside slots, with bonus-buy features that would exceed it disallowed. Bonus funds work on slots only.
Wagering is comparatively light for the segment: 30x deposit-plus-bonus on the welcome and its spin winnings, and 20x on the weekly spins, each within their stated windows.
Free-spin winnings from the welcome can release up to €150 per daily batch to the real balance.
Each offer is limited to one per person, household, IP address, email, and phone number, and VPN use is prohibited.

The Bottom Line

Bison Casino is the most readable casino of its type in this segment. It names the prize slots, states the per-spin value rather than leaving it to estimate, holds a verifiable Curaçao Gaming Authority licence, and runs wagering that is light by the standards of the field — 30x on the welcome and only 20x on the weekly spins.

The win rules are also relatively player-friendly. Free-spin winnings can release up to €150 per daily batch, which is more generous than the €50–€100 caps common elsewhere, and Casino Guru found no unfair terms and no relevant complaints, awarding a 9.2 Safety Index.

The one practical constraint is the €2 maximum bet, which is lower than most rivals and includes in-slot gambling features, so the wagering has to be cleared in small stakes.

For a player who reads terms and values transparency and a real licence over a flashier headline number, Bison is a straightforward, well-disclosed option — clear the spins methodically and the €150 daily ceiling is the main figure to keep in view.

FAQ

Do I need a bonus code at Bison Casino?

No. Neither offer uses a bonus code. For the welcome bonus, you select it on the deposit page before making your first deposit. For the weekly free spins, a qualifying deposit of at least €10 credits the spins automatically, with no code required.

What is the maximum win from the Bison Casino free spins?

Free-spin winnings from the welcome can release up to €150 to your real-money balance per daily batch of spins. The casino does not state an overall maximum cashout on the welcome beyond this, though general withdrawal limits may apply. Free-spin winnings clear at 30x on the welcome and 20x on the weekly offer.

Can I win unlimited sums with the Free Spins?

The welcome free spins are credited on Trout’s Treasure – Wild Rivers. The weekly free spins rotate among named titles each week — 3 Energy Diamonds: Hold And Win, 3 Gods Unleashed: Hold And Win, or Mole In The Hole — and the spins from each offer can only be used on the assigned slot.
