Infinite X Slot Review
A rubber duck sits on a window ledge halfway up a pixel-art tower, a cactus keeping it company on the sill below, while a little climbing figure works his way past air-conditioning units towards a flat-blue city skyline. Infinite X, from Million Games, is the rare casino game where the maths never makes a decision for you: Joe climbs, the multiplier grows, and every single stopping point along 320 steps is yours to call.
That’s a bolder direction than the studio’s more conventional East West Wilds. Infinite X runs at 96.32% RTP, spreads its climb across 40 building levels, and hands you the brake at all times.
Base Game & Features
Infinite X is a progression-based instant-style game. There are no reels, no paylines and no symbol matches; the goal is simply to climb as high as possible before cashing out. You pick a bet, press Start, and Joe begins his ascent of the building one step at a time.
A round plays out in the same basic sequence every time, and the whole thing takes seconds to learn:
- Select your bet amount
- Press Start to begin the climb
- Watch Joe move up the building step by step, with every step consuming energy
- Collect energy crates automatically as Joe passes them, refilling his tank
- Reach a new level every eighth step, increasing your multiplier
- Cash out at any time to secure your current multiplier and winnings
The Building and the Ladder
The building is the game board, and it’s a big one. The ladder Joe works his way up is built from a handful of fixed numbers:
- 320 steps in a full climb
- 40 building levels
- A new level every eighth step
- A multiplier increase each time Joe reaches a new level
- A multiplier scale running to 1000x at the top of the tower
The counter tracks his progress as steps out of 320, so you always know exactly where you are on the building. The multiplier ladder sits alongside the climb on the right of the screen, marking how far the payout scale extends and how much of it Joe has actually earned.
Energy and Crates
Energy is the resource that governs everything. Each step drains a little of it, and when the tank runs dry the climb stops in its tracks. Joe can’t fail and he can’t fall; the only thing that ends a climb is empty energy.
Energy crates appear on the way up, and Joe collects them automatically. Each crate refills part of the tank and buys him more steps, which makes them the difference between a short climb and a long one. You don’t choose to grab them; they’re part of his route.
That balance is what gives a round its shape. A lucky run of crates can carry Joe through several levels without pause, while a barren stretch of wall leaves the meter falling and the decision pressing. How much energy a climb starts with, and how generously the crates arrive, determines how far any single round can realistically go before the rebuy question arrives.
Infinite X Bonus Features
The whole game lives in one decision: when to stop. You can cash out at any point during the climb and bank your current multiplier and winnings, and nothing forces your hand. The STOP button is always there, and it carries a fraction alongside the word STOP that shifts as the climb progresses, a running marker of where a press would leave you.
Cashing Out
Cashing out secures everything Joe has earned to that point. It’s the safe play, and after a long climb it’s often the right one, because the alternative is watching the energy meter decide your fate a few steps from the next level.
The cash-out banner shows the figure you’d be banking in real time, so the temptation is always quantified. That’s a smart piece of design; it keeps the amount you’re risking in front of you at every step rather than leaving you to do the arithmetic mid-climb.
Rebuys
If Joe does run out of energy, the round isn’t over. There are exactly two ways out of a stalled climb:
- Cash out your current winnings and end the round
- Pay for a rebuy and continue from Joe’s current position with a refilled energy tank
The rebuy cost climbs alongside Joe, so each one costs more than the last. That escalating price is what makes the late climb interesting. A rebuy near the top is expensive, but it protects a multiplier that took hundreds of steps to build. Fold the two decisions together and every level becomes a small negotiation with yourself.
Our Honest Verdict
Overall Rating: 7.7/10
Playing Infinite X feels less like a spin and more like a long hold of your breath, with a pixel-art tower scrolling past and a rubber duck judging you from a window ledge. The one reason to pick it up is that it puts you in charge in a way almost nothing else on a casino menu does: nothing ends a climb but your own choice or an empty tank.
Its best idea is the escalating rebuy. Because staying in costs more the higher Joe goes, the late-game decisions carry genuine weight, and a single climb can turn into a proper test of nerve. Its worst is that between those moments there’s a lot of waiting: the multiplier only shifts every eighth step, and the crates arrive on the building’s schedule, never yours.
This is a game for people who’d rather make a decision than watch a spin, and who don’t mind a slow build to a big call. Chasers of bonus rounds and symbol wins will find nothing for them here. For the patient type, though, Joe’s tower is good company, one ledge at a time.
