Thunder Vault: Hold & Win

Thunder Vault: Hold & Win strips the hold-and-win mechanic down to a 3x3 grid from Novomatic: 5 paylines, a 94.12% RTP, high volatility, and a bonus where golden coin symbols land on the outer reels with cash values or jackpot tier names printed on their faces. When those coins trigger the Hold & Win round, they freeze while the remaining positions respin until no new coins arrive. Play on desktop and mobile at Wild.io with crypto.

What is Thunder Vault: Hold & Win?

Thunder Vault: Hold & Win is a 3x3 video slot from Novomatic with a 94.12% RTP, high volatility, 5 paylines, and a Hold & Win bonus triggered by golden coin Bonus symbols landing on reels 1 and 3. Each coin displays a cash value or a jackpot tier label, and a Collector symbol can boost the total accumulated during the respin phase.

The 3x3 format concentrates the action. Base-game fruit symbols fill the grid and pay on the 5 fixed lines when they match from left to right. The real mechanic is the bonus: Bonus coin symbols appear only on reels 1 and 3, and when they both show up in the same spin they kick off the Hold & Win sequence. The Collector symbol adds to the total any values already accumulated. High volatility on a 3x3 grid means low win frequency in the base game, but the hold-and-win bonus is where the slot is designed to pay.

Who will enjoy this game the most?

You will probably enjoy this game if you like:

• Hold & Win fans who prefer a compact 3x3 grid over a sprawling 5-reel layout

• Classic fruit machine players who want a traditional symbol set combined with a modern respin feature
• Jackpot seekers targeting fixed prize tiers awarded during the Hold & Win phase
• Crypto players at Wild.io wanting a fast-loading, mobile-compatible hold-and-win slot

Thunder Vault: Hold & Win Slot Theme & Graphics

Thunder Vault builds its visual identity around classical electricity imagery: lightning bolts, glowing arcs, and vault-door steel textures underlie the reel grid. The base-game fruit symbols sit against this charged backdrop, giving the game a contrast between the familiar (cherries, lemons, sevens) and the dramatic thunder-and-vault concept the title suggests.

The Bonus coins are the visual centrepiece: oversized golden discs that fill a 3x3 grid position with obvious weight, their printed cash values or jackpot labels readable at a glance. Novomatic designed the 3x3 layout to feel immediate, and the compact grid suits mobile play well. Touch targets are large, and the Hold & Win animation of coins locking into place works cleanly on phone-sized screens without needing separate portrait mode adjustments.

Thunder Vault: Hold & Win Slot Symbols & Paytables

Thunder Vault: Hold & Win uses two distinct symbol layers: a classic fruit machine set for base-game payline wins, and functional Bonus coins that drive the Hold & Win mechanic.

Low Value Symbols

The base-game low symbols are classic fruit machine icons: cherries at the lowest pay tier, followed by lemons and oranges. On a 3x3 grid with 5 paylines, these appear frequently but pay modest amounts per combination. They represent the session's steady background activity between bonus triggers.

High Value Symbols

The higher-value base symbols include bells and lucky sevens. Lucky sevens sit at the top of the regular pay table, delivering the largest payline win available outside the Hold & Win bonus. Bells pay below sevens, and both appear less often than the fruit symbols, creating clear payout steps up the hierarchy.

Special Symbols

The golden coin Bonus symbol is the game's most important piece. It appears only on reels 1 and 3. Each coin carries a printed cash value or a jackpot tier name on its face. When these coins land on both their designated reels in the same spin, the Hold & Win bonus starts. During the respin sequence, each coin that lands in any of the nine grid positions freezes in place and adds its face value to the running total. The Collector symbol, when it lands during the Hold & Win phase, picks up the combined value of all coins already frozen and adds that sum to the prize pool, effectively doubling the contribution of every coin accumulated to that point.

Thunder Vault: Hold & Win Bonus Feature & Special Features

Hold & Win Bonus

The Hold & Win bonus triggers when golden coin Bonus symbols land on reels 1 and 3 in the same base-game spin. All coins freeze in their positions, and the remaining eight grid spaces respin. Each respin either delivers new coins, which lock in place and add their face values to the total, or ends the sequence if no new coins land. The bonus continues as long as coins keep appearing. Jackpot tier symbols among the coins award their named fixed prize in addition to cash accumulation. The Collector symbol, if it lands during the respins, takes the sum of all currently frozen coins and adds that amount again to the prize pool. The combined cash total and any jackpot prizes are paid when the sequence ends.
