15 Hammers Hold & Win Game Features

These are the fun features that can appear with each spin of the reels:

15 Hammers Hold & Win Wild Symbol Feature

Wild symbols appear during the base game and bonus spins, and substitute for standard symbols to help complete winning combinations. If you land five of them on a payline, they also have a symbol payout of 75x the bet.

15 Hammers Hold & Win Bonus Feature

The Hold & Win feature is randomly triggered when Hammer symbols land during the base game. These Hammers can land as single 1×1 symbols, or colossal 2×2 and 3×3 symbols. The 2×2 variant counts as four symbols, while the 3×3 variant counts as nine. Once activated, the reels reset into a locked grid made up of empty spaces and six Hammer symbols.

The feature begins with three respins and all Hammers from the trigger locked in place. Any new Hammers that land during the feature will lock in place and reset the respin count to three. Each Hammer pushes you further up the prize ladder, which includes four jackpot tiers. The feature ends when you run out of respins or when you fill the grid with hammers. Filling the grid will award the game’s top jackpot prize.

15 Hammers Hold & Win Buy-In Feature

For those who like to dabble in some side bet action, the game provides two convenient buy-in options. The Double Chance option, played at 1x the base bet plus an additional 0.4x the base bet, doubles the likelihood of triggering Hold & Win during the base game. The Buy Feature option gets you straight into the Hold & Win feature for 60x the base bet.

15 Hammers Hold & Win Slot Bonuses and Jackpots

This game uses a fixed-jackpot structure with tiers on the Hold & Win prize ladder. The Mini, Minor, Major, and Grand jackpots fill in the prizes for eight, 10, 13, and 15 hammers collected in the Hold & Win round. Their prizes are valued at 10x for the Mini, 25x for the Minor, 50x for the Major, and 1,000x for the Grand. In combination with base game wins leading up to the feature round, the highest prize you can achieve is 1,283x the bet.

How To Win the 15 Hammers Hold & Win Slot

You’ll create winning combinations by matching symbols across the game’s five fixed paylines. Paylines start on the first reel and move from left to right. Only the highest win per payline is paid out, but multiple lines can be won together. Wilds can help you unlock additional wins by substituting for paying symbols. Additional payouts are available by climbing the prize ladder during the Hold & Win Bonus feature.

15 Hammers Hold & Win Game Graphics and Design

The game uses the Viking theme in a unique way. Instead of the traditional gods and ancient battle mythology, the game tells the story of Vikings setting off on their raids. The aesthetic uses softer textures in a stylized, illustrative format, with bright colors and subtle animations.

The game is set on a pier facing the harbor before the Vikings set sail, with longships docked in bright blue water between the mountains surrounding a village. The reels and prize ladders are mounted to a weapon rack, with a Viking captain covered in glowing runes standing between the prize ladders.

The Viking captain is lightly animated to give the main game grid some movement, while the longships bob in the water behind it. A cheerful flute melody carries the traditional soundtrack, featuring rhythmic drum beats and guttural chants.

15 Hammers Hold & Win Slot Symbols

Low-value symbols include standard card ranks, while higher-value symbols are themed around Viking gear such as horns, rings, and helmets. Card ranks 10, J, and Q have a top prize of 1x your wager, while the K and A pay 2x your bet for five-of-a-kind. The horn, axes, ring, and helmet pay 3x, 3x, 5x, and 10x for a full payline.
