Monster Triple on gt99 is built for players who want more from every spin. Three independent reel sets, monster wild symbols, and a bonus system that can stack multipliers across all three boards at once — this is high-volatility slot gaming done right.
Most slot games give you one set of reels and ask you to watch the same grid spin over and over. Monster Triple on gt99 throws that formula out entirely. The game runs three independent 3x3 reel sets side by side on a single screen, each one spinning simultaneously with every bet you place. That means three chances to hit a winning combination on every single spin — and when all three boards fire at once, the payouts can get very large very quickly.
The monster theme is more than just decoration. Each reel set is guarded by a different creature — a fire monster, a storm monster, and an ice monster — and each one has its own wild symbol behaviour. The fire monster wild expands vertically, the storm monster wild duplicates itself to an adjacent reel, and the ice monster wild freezes in place for one additional spin after it lands. Understanding how each monster behaves is key to getting the most out of the game.
GT99 has positioned Monster Triple as one of its flagship high-volatility titles. That means the wins don't come on every spin, but when they do hit — especially during the triple bonus round — the amounts can be genuinely impressive. Players in Bangladesh who enjoy the tension of a high-stakes spin will find this game very much to their taste.
The game is available on gt99 around the clock, with no download required. You can play directly in your mobile browser or through the gt99 app, and the triple-reel layout scales cleanly to any screen size without losing clarity.
One bet, three boards, three independent outcomes. Here's how the three reel sets work together on gt99.
The fire wild expands to fill the entire column it lands on. A single fire wild on reel 2 can complete multiple paylines simultaneously, making it the most straightforward of the three monster wilds.
The storm wild copies itself to one random adjacent reel position after landing. This can create two wilds from one symbol, and if both copies land on high-value positions, the payout jumps significantly.
The ice wild stays locked in position for one extra spin after it first appears. This gives you a guaranteed wild on the following spin, which pairs well with the free spins round when triggered on this board.
Each reel set shares the same base paytable. Wins from all three boards are added together at the end of each spin. Here's what the key symbols pay per board at your current bet level.
| Symbol | Type | 3 of a Kind | Board Multiplier |
|---|---|---|---|
| Triple Monster | Premium | 20x bet | 3x all boards |
| Fire Wild | Wild | Substitutes all | Expands column |
| Storm Wild | Wild | Substitutes all | Duplicates adjacent |
| Ice Wild | Wild | Substitutes all | Sticky +1 spin |
| Skull Crown | Scatter | Free Spins | Triggers bonus |
| Dragon Eye | High | 8x bet | Standard |
| Venom Fang | Mid | 5x bet | Standard |
| Iron Claw | Low | 2x bet | Standard |
Beyond the triple reel setup, Monster Triple on gt99 packs in several bonus mechanics that keep every session feeling fresh.
Land skull crown scatters on two or more boards in the same spin to trigger the Triple Free Spins round. All three reel sets spin simultaneously for 12 free spins, with each board's monster wild active throughout. Retriggers are possible with no cap.
When all three boards produce a winning combination on the same spin, a cross-board multiplier activates. The base multiplier starts at 3x and increases by 1x for every subsequent all-board win, up to a maximum of 50x during the free spins round.
Fill all nine positions on any single board with the same monster wild type to trigger the Monster Jackpot. This is a rare event but the payout is fixed at 500x your total bet, making it one of the biggest single-spin prizes available on gt99.
Once per session, you can activate the Board Swap feature, which reshuffles the monster assignments across the three reel sets. This is useful if one board has been cold for a while and you want to change the dynamic without ending your session.
Enable Turbo Spin to cut the animation time in half. All three boards resolve faster, which is ideal for players who prefer a higher number of spins per session rather than watching every animation play out in full detail.
The triple-board layout is fully responsive. On smaller screens, the three reel sets stack vertically for easy viewing, and the touch controls are large enough to use comfortably without zooming in. Works great on the gt99 app too.
These ratings are based on player feedback collected from gt99 users in Bangladesh over the past six months. High volatility games tend to score lower on bonus frequency but higher on win potential — Monster Triple is no exception.

"I've played a lot of slots on gt99 but Monster Triple is something else. When all three boards hit at the same time and the cross-board multiplier kicks in, the feeling is incredible. Hit a 22x multiplier last week and it was a very good night."
"The ice wild sticky mechanic is my favourite part. You land it, and then you go into the next spin already knowing one board has a wild locked in. It changes how you think about each spin. GT99 picked a good one with this game."
"High volatility means you have to be patient, but gt99 makes it easy to manage your budget with the session limits. I set my limit, play Monster Triple for an hour, and I never go over. The triple free spins round is worth waiting for."
