Chain Reaction Hold & Blitz ItemsThree Coins Trigger Hold & Blitz Across All Nine Reels
Landing three Coins on a single reel activates Hold & Blitz across all nine reels at the same time. Each reel receives its own three-spin counter, and landing another Coin on a reel resets that reel’s counter back to three.
The official Gamesheet lists a Hold & Blitz hit rate of 1 in 160, changing to 1 in 69 with Ante Bet.
Filled Reels Launch the Chain Reaction
Completing an entire reel activates the Chain Reaction feature. The filled reel fires bolts of electricity toward other reels, and reels struck by those bolts are guaranteed to receive additional Coins.
Filled reels can also be powered up by a random multiplier value, adding another reward element to the Hold & Blitz sequence.
Four Jackpot Milestones Join the Feature
Chain Reaction Hold & Blitz includes four fixed jackpot milestones. The Mini is worth 15×, the Minor 50×, the Major 150×, and the Mega 1,000×.
These jackpot levels sit alongside the Coin-based Hold & Blitz system and the Chain Reaction mechanic as part of the game's main bonus structure.
Ante Bet and Buy-In Offer Faster Access
The optional Ante Bet doubles the chance of triggering Hold & Blitz, moving the published feature hit rate from 1 in 160 to 1 in 69.
A separate Buy-In provides direct access to Hold & Blitz. Combined with nine independently running feature counters, Chain Reactions and random multiplier upgrades on completed reels, the feature forms the core of the game's 12,500× maximum win potential.
Chain Reaction Hold & Blitz is rated High volatility, offers RTP variants of 95%, 93% and 91%, and supports stakes from 0.10 to 20.00. The network launch is scheduled for October 14, 2026.
