Colossus: Hold & Win

Colossus: Hold & Win Slot Review

Pack yourselves a suitcase, iSoftBet is flying us to Ancient Greece in search of those big wins with Colossus: Hold & Win. Released on 20 January 2022, this mythological-themed slot delivers the studio’s signature Hold & Win mechanic paired with powerful Stacked Multiplier Wilds. The 96% RTP and high volatility mean wins are less frequent but potentially substantial. This game appeals to players who love the respin formula and don’t mind volatile gameplay in pursuit of that elusive 10,000x jackpot.

Base Game & Features

Colossus: Hold & Win is a 5-reel, 3-row slot with 20 fixed paylines. The Ancient Greece theme runs through the entire game, with detailed symbols reflecting mythological elements. Bets range from £/€0.20 to £/€20, making it accessible for both casual players and those wanting higher stakes. The 37.2% hit frequency ensures reasonable action between bigger wins, which helps manage your bankroll during extended play sessions.

Colossus Wilds & Multipliers

The standout feature of the base game is the Colossus Wilds, which land on reels 2-5 and transform into Stacked Multiplier Wilds. Each wild receives a random multiplier of 2x, 3x, 5x, or 10x. When multiple wilds land together, their multipliers multiply by each other before being applied to your win, potentially creating some seriously impressive base game payouts. This feature alone keeps the base game genuinely exciting and rewarding.

Bonus Features & Respins

Colossus: Hold & Win doesn’t feature traditional free spins. Instead, the game revolves around the Hold & Win respin mechanic, a formula that iSoftBet has successfully deployed across their portfolio. Land 6 or more Gold Coin symbols to trigger 3 respins. Each time you land additional coins during the respins, the respin counter resets to 3, giving you more chances to fill the grid. The mechanic feels dynamic and keeps tension high as you chase bigger coin values.

During the Hold & Win feature, the Colossus Rising Flame modifier randomly awards multipliers (2x, 3x, 5x, or 10x) to your coin symbols. These multipliers are applied to the final coin values collected, potentially transforming decent wins into massive ones. The feature progresses at a reasonable pace–not frantic, but not glacially slow either–giving you time to appreciate what’s happening on screen.

Jackpot Prizes

The Colossus Spin Jackpot triggers when you fill the entire grid with coin symbols. A jackpot wheel then determines your prize from three tiers: Minor (50x bet), Major (500x bet), or Colossus (10,000x bet). The theoretical maximum win reaches 26,305x through optimal feature combinations, though the 10,000x Colossus jackpot represents the primary guaranteed maximum. Our team found that reaching the jackpot is genuinely thrilling, and the potential for 10,000x makes every Hold & Win feature feel meaningful.

Bonus Buy & Ante Bet

For international players, the Bonus Buy feature lets you activate the Hold & Win feature immediately for 100x your current stake. This increases the RTP to 96.95%, slightly higher than the base game’s 96%. However, this feature is not available to UK players due to regulatory restrictions. UK players must trigger the Hold & Win naturally through the 6+ coin symbols requirement, which keeps the focus on gameplay discovery rather than paid shortcuts.

Our Honest Verdict

Colossus: Hold & Win earns a solid 7/10. iSoftBet has executed the Hold & Win formula well here, combining solid mechanics with impressive visuals and the ever-present potential for substantial wins. The Colossus Wilds and Multiplier system elevate the base game beyond standard fare, and the Hold & Win respin feature remains genuinely engaging. However, the game doesn’t break new ground–it’s a competent refinement of a now-familiar formula rather than an innovation. We’re starting to wonder when enough is enough with Hold & Win games across the industry, though that’s more industry fatigue than a failing of this specific slot.

The Ancient Greek theme is executed well with top-notch graphics and immersive sound design that suits the gameplay perfectly. The 37.2% hit frequency combined with high volatility creates an interesting balance–wins land fairly regularly, but you’ll still encounter dry spells. Players who prefer Megaways or Twisted Tale series games might find this Hold & Win iteration a bit tame compared to iSoftBet’s more innovative offerings, but for Hold & Win enthusiasts, this is a quality addition to the studio’s catalogue.

Mobile compatibility is excellent thanks to the HTML5 technology, so you can enjoy Colossus: Hold & Win on iOS, Android, or desktop without compromising experience. Our team found moments where the game surprised us with some genuinely exciting multiplier combinations, proving the mechanics have merit. Not a bad game by any means–just not revolutionary.
