In the competitive world of online slots, spin bonuses are what keep players coming back. From free spins to multipliers and interactive bonus rounds, the best slot games go beyond basic gameplay by offering exciting rewards that can boost both engagement and winnings.
If you’re looking for slot games that offer the best spin bonuses, here are seven top picks known for their generous features, creative design, and big-win potential.
1. Starburst (NetEnt)
Bonus Type: Expanding Wilds + Re-spins
One of the most iconic slot games, Starburst is famous for its simplicity and explosive spin bonuses. When the Starburst Wild lands, it expands across the reel and triggers a re-spin—sometimes chaining into multiple re-spins and big wins.
2. Book of Dead (Play’n GO)
Bonus Type: Free Spins + Expanding Symbol
Triggering 10 free spins with a special expanding symbol, Book of Dead offers high-volatility excitement. If the chosen symbol is a high-value character, full-screen wins are possible—and massive.
3. Gonzo’s Quest Megaways (Red Tiger)
Bonus Type: Free Falls + Increasing Multipliers
This Megaways version of the classic game delivers up to 117,649 ways to win. The Free Falls bonus round offers up to 9x multipliers on consecutive wins, making every spin potentially more valuable than the last.
4. Bonanza (Big Time Gaming)
Bonus Type: Free Spins + Unlimited Win Multiplier
Bonanza pioneered the Megaways format, and its bonus spins are legendary. Trigger 12 free spins with an unlimited multiplier that increases after every cascade. It’s high variance, high reward.
5. Dead or Alive II (NetEnt)
Bonus Type: Three Free Spins Modes
Known for its huge win potential, Dead or Alive II offers three different free spins features, each with its own volatility level. Wilds can become sticky, increasing chances of full-reel coverage and massive payouts.
6. Reactoonz (Play’n GO)
Bonus Type: Chain Reaction Bonuses + Quantum Features
A unique grid-based slot, Reactoonz builds up bonuses as you create cascading wins. The Quantum features (Implosion, Demolition, Alteration, and Gargantoon) unleash bonus effects that can take over the grid.
7. Jammin’ Jars (Push Gaming)
Bonus Type: Free Spins + Sticky Wild Multipliers
Jammin’ Jars offers a vibrant experience where wild jars stay on the board during free spins and build multipliers with each win. Chain reactions and multipliers can lead to huge, unpredictable wins.
