OnlySpins Bonus Codes December 2025

OnlySpins Casino Bonuses for New and Existing Players

OnlySpins keeps things interesting with a mix of welcome bonuses, reloads, cashback offers, and gamified rewards. New players can choose between two main welcome deals: a 100% match up to $750 (AUD/NZD/CAD) or €500 plus 200 free spins (credited as 20 per day for ten days), or a 200% crypto bonus up to 3,000 USDT with a minimum deposit of 100 USDT.

All welcome bonuses are sticky, meaning both the deposit and bonus amount must be wagered 35x, while free spins have 40x wagering. In testing, I found the terms clearly displayed and the bonus credited instantly, though clearing it does require significant play.

Ongoing rewards include weekend reloads (50% up to $1,050), weekday free-spin offers, crypto reloads (60% up to 1,000 USDT at 30x), and live-casino cashback (25% up to $300 at just 1x). You’ll also find regular tournaments, the playful Bonus Crab mini-game, and VIP cashback starting from Level 3. The variety is solid, and while some offers have higher wagering than others, OnlySpins makes the terms transparent and easy to find.

OnlySpins Casino Bonus Rules and Fairness

OnlySpins operates under an Anjouan Gaming Authority licence and uses SSL encryption to protect personal and financial data. All bonus details, including wagering, expiry, and eligible games, are shown upfront before confirming a deposit. The transparency here builds trust, and in my experience, support staff were quick to clarify any bonus-related questions.

While the sticky structure means you’ll need more playtime to unlock winnings, the terms are fair and consistent across promotions. Cashback offers in particular stand out for having low or single-turn wagering, which makes them a safer choice for steady returns.

The range of promotions,  especially the low-wagering cashback and crypto reloads, gives you flexibility in how you play.
