Treasure Vault (Booming Games) – Review & Demo Play

Treasure Vault Slot Overview

I step into a bank vault stuffed with gold, gems, and jewellery, and Treasure Vault leans into the heist mood straight away. The 5 reels run with 30 fixed bet ways, framed by piles of bullion. An upbeat country soundtrack clicks with the rhythm and ramps up when features land. The look is charming, if hardly fresh, yet it’s slick and fully optimised for mobile and desktop. Stakes range from £0.30 to £18 per spin, so I can set sessions sensibly.

Volatility sits high, though the 28.9% hit ratio keeps base play busy enough for me. RTP lands at 95.1%, below the line, so I keep an eye on balance swings. The max win caps at 8,000x the bet, which suits the risk profile. Stacked diamond Wilds help stitch wins together. Free Spins with eliminations and upgrades carry real weight over time. Cash Collect drops random bet multiplier pops between bonuses, so momentum rarely feels stalled.

Treasure Vault Slot Features

Cash Collect fires on any paid spin. Cash symbols can appear stacked on reels 1 to 4, each showing a random bet multiplier from 1x to 50x. If a Collect symbol hits on reel 5 at the same time, all visible values are gathered and paid at once. I have seen single reel stacks line up for tidy bursts, and it helps the base game breathe when bonuses take longer to arrive.

Free Spins trigger when 3 Scatters land together on reels 1, 3, and 5, awarding 12 free games. Land 3 more during the bonus to add +6 extra spins, with no cap. When minor symbols form a win, that symbol is removed for the rest of the feature. Each elimination triggers a cascade, clearing all winning symbols to tumble new ones into place. Wilds involved in low wins also drop out, which keeps the reel set tightening.

Major symbol wins do something different. They upgrade the winning symbols to golden versions that pay double their regular value, yet they do not trigger cascades. The audio kicks up a notch here and the pace feels lively without losing control. With stacked elements still in play, this round can open lanes to the top end if the upgrades land in step with retriggers. I have seen runs where a single premium keeps upgrading across added spins. Big clusters are rare, but value per hit rises fast when it sticks.

The paytable keeps it classic. A–10 card ranks sit low, paying around 1.16x to 2x your bet for five of a kind. Premiums climb through coins, gold watches, gold bars, and crows, where five-of-a-kind can reach from 4.16x up to 133.33x your bet. Diamond Wilds appear on all reels, substitute for regular symbols, and can land in stacks, partially or fully visible. That stacked behaviour supports base spin consistency across the 30 paylines.

Treasure Vault - Review Summary

Treasure Vault looks familiar, yet the package works. Stacked Wilds can land at any stage, random Cash Collect adds sharp bursts, and Free Spins with symbol eliminations and upgrades push rewards higher. I rate the feature flow, even if the theme is a typical bank heist. The lower-than-average RTP is the trade you make for the 8,000x ceiling, so balance management matters when variance bites. Hit ratio at 28.9% keeps sessions from feeling barren.

In practice, I’ve had steady sessions thanks to the 28.9% hit ratio, then watched the bonus turn minor wins into proper streaks once removals start chaining. The upgrade to golden versions is a tidy touch that doubles key premiums. Betting from £0.30 to £18 gives enough room to scale. For me, this is an action-led slot where the feature set lifts the mood and keeps the reels moving. Mobile play runs smooth and timing feels fair.
