15 Hammers: Hold & Win
Embark on a Viking longship voyage in 15 Hammers: Hold & Win, a new slot from Octoplay. While these Nordic warriors are often depicted as rough, they historically took great pride in their appearance, using grooming as a sign of status. This game offers a chance to discover a more refined side of these fierce explorers while you pursue thunderous wins and potential rewards of up to 1,283 times your original bet.
15 Hammers: Hold & Win Gameplay and Mechanics
15 Hammers: Hold & Win is built on a classic 5-reel, 3-row grid, offering 5 fixed paylines for winning combinations. The base game is energised by the landing of colossal 2×2 and 3×3 Hammer symbols, which build momentum towards the slot’s central feature.
The core bonus is the Hold & Win round, triggered when six or more Hammer symbols land simultaneously. In this feature, the reels reset, and players aim to fill all positions with up to 15 hammers to climb a Cash Ladder. This pursuit offers massive payouts, culminating in the Grand Jackpot, with potential wins reaching 1,283x the stake. Players can also opt for a Double Chance or a Feature Buy to directly access this thrilling bonus action.

15 Hammers: Hold & Win Slot Features
Ready to unleash the slot’s divine mechanics? Discover the features that can trigger legendary wins on your voyage.
Wild Symbol
The Wild acts as an ally, substituting for all regular symbols to help form winning combinations. While it cannot replace the special Hammer Symbol, landing a full line of five Wilds yourself delivers a direct payout of 75x your stake.
Hammer Symbols
Three sizes of Hammer symbols exist: 1×1, 2×2, and 3×3. On any spin, only one large hammer can land–either a 2×2 (which splits into four 1×1 hammers) or a 3×3 (which splits into nine). Each hammer that lands charges the character above the reels, though this animation is purely for entertainment.
When enough energy is gathered to trigger the Hold & Win bonus, the reels transform until at least six Hammer symbols are present to begin the feature.
Hold & Win Bonus
This bonus is guaranteed when six or more Hammer symbols land simultaneously. You begin with 3 free spins, where only Hammers and empty spaces appear. Every time a new Hammer lands, it locks in place and resets your spin count back to 3. The feature continues until you run out of spins or achieve the ultimate victory: filling the entire grid with 15 hammers, which ends the round.
Cash Prizes
Your final reward in the Hold & Win feature is determined by the total number of Hammer symbols you collect, with payouts awarded on a cumulative ladder. This means you receive the prize for your achieved level plus all prizes from the tiers below it. The full payout structure is as follows:
- 6 Hammers: 3x Stake
- 7 Hammers: 5x Stake
- 8 Hammers: 10x Stake
- 9 Hammers: 15x Stake
- 10 Hammers: 25x Stake
- 11 Hammers: 30x Stake
- 12 Hammers: 40x Stake
- 13 Hammers: 50x Stake
- 14 Hammers: 100x Stake
- 15 Hammers: 1000x Stake
Double Chance
For an additional cost of 40% of your current bet, you can activate the Double Chance feature. This doubles your probability of triggering the Hold & Win bonus game and increases the game’s RTP to 95.80% for that spin.
Buy Feature
Skip the wait and go straight to the action with the Feature Buy. For a cost of 60x your stake, you can instantly trigger the Hold & Win bonus round. This purchase comes with a slightly elevated RTP of 95.89%.
| Features | Description |
| High-Paying Symbols | Horn, axes, a blue ring, and a helmet pay between 15x and 50x for landing 5 matching symbols. |
| Low-Paying Symbols | 10, J, Q, K, and A award between 5x and 10x for a 5-of-a-kind hit. |
