Robots and post-apocalyptic settings are all the rage all the time. ELK Studios has capitalised on this theme with a new game. In our Tinkerbot slot review, we will take apart this cluster pays slot that takes you on a journey through a post-apocalyptic scrapyard where discarded machinery can be your treasure. Released recently in January 2025, the game features a 5x5 grid that can expand up to 7x7. There is a unique evaluation system based on clusters rather than traditional paylines. With an RTP of below-average 94% and medium volatility (6/10), Tinkerbot carries a max win potential of up to 10,000x your bet. The bet range is a comfortable £0.20 to £100 and the game has an array of interesting features—cascading wins, multisymbols, Botboxes, and grid expansions.
Tinkerbot features a unique cluster pays layout with a default 5x5 grid that can expand up to 7x7, rather than traditional paylines. Instead of fixed paylines, wins are formed by matching clusters of five or more symbols that are connected horizontally or vertically.
You can set your bet anywhere from £0.20 to £100 per spin—so both conservative bettors and high rollers have options here.
The slot game has a relatively low RTP of 94% and a medium volatility (6/10). This means that the wins may be fewer and far apart but can cascade into larger payouts when you least expect them to.
Despite the unconventional structure, Tinkerbot has a maximum win potential of up to 10,000x your stake. This makes it an appealing choice for those who enjoy risk and innovative gameplay mechanics.9

The post-apocalyptic scrapyard setting where discarded tech and relics are transformed into winning treasures hits the sweet spot. The design is gritty yet vibrant, accentuated with neon glows that highlight the rusted machinery against a dark industrial backdrop.
The audio blends mechanical clanks with futuristic synth beats. Ultimately, you end up in a world of inventive chaos.
On the grid, the lower-paying symbols appear as colourful box items in blue, green, and purple. The high-paying symbols are represented by various futuristic gadgets in blue, green, pink, and red. In the payout table below, I have tried my best to give names to these gadgets. But I highly recommend you check the paytable in the game to remember the symbols.
Blue
5x = 0.1x / 6-7x = 0.15x / 8-9x = 0.25x / 10-11x = 0.5x / 12-14x = 1x / 15x+ = 10x
Green
5x = 0.15x / 6-7x = 0.2x / 8-9x = 0.35x / 10-11x = 0.75x / 12-14x = 1.5x / 15x+ = 15x
Purple
5x = 0.25x / 6-7x = 0.3x / 8-9x = 0.5x / 10-11x = 1x / 12-14x = 2.5x / 15x+ = 25x
Flying Pod
5x = 0.5x / 6-7x = 0.75x / 8-9x = 1x / 10-11x = 2x / 12-14x = 5x / 15x+ = 50x
Triple Barrels
5x = 0.75x / 6-7x = 1x / 8-9x = 1.5x / 10-11x = 3x / 12-14x = 7.5x / 15x+ = 75x
Mini-Copter
5x = 1x / 6-7x = 1.5x / 8-9x = 2.5x / 10-11x = 5x / 12-14x = 10x / 15x+ = 100x
Slot Machine
5x = 1.5x / 6-7x = 2.5x / 8-9x = 3.75x / 10-11x = 7.5x / 12-14x = 10x / 15x+ = 150x
On mobile, Tinkerbot becomes an elegant slot game with minimal on-screen controls to help keep the focus spread on the 5x5 (up to 7x7) reels. The icons are smaller and high resolution, looking crisp on any type of mobile screen. Furthermore, all bonus features and functionality appear very smooth and snappy, including the subtle up-down animation of some symbols.
All in all, ELK Studios has made an excellent slot game that is perfectly mobile-responsive.
There are several bonus features here such as Absorb, the Bonus symbol, Transform, the Botbox, and the Arrow-X-W features. Connecting 5 or more symbols horizontally or vertically will generate a win (Cluster Wins mechanic). There is also a multiplier, the value of which is applied to all winning symbol clusters.
There is a Bonus symbol shaped like a B (like the Wild is shaped like a W). 3 of these symbols trigger the bonus game with 7 free drops. Unused Botboxes are kept between free drops. The current multiplier value and the grid size are both persistent between free drops. With 4 Bonus symbols, you will trigger the Super Bonus Game with 9 free drops. This game is always played at the maximum grid size and with a boosted multiplier value.
The Botbox mechanic is the hero of the show. Each winning cluster generates a Botbox. Three or more of these activate a feature release where every Botbox releases a random feature. There is also a special type of Botbox called the instant Botbox. It will always release a random feature on its own.
The features include Absorb (selects one paying symbol and collects all identical symbols to create one Multisymbol) and Transform (selects one paying symbol and transforms all identical symbols into another type). These two symbols give rise to ample chaos on the reels.
The Wild symbol substitutes for any payout symbol. Removing all payout symbols on the game grid awards a random amount of extra Botboxes in addition to Botboxes created from the cluster wins. Also, there is a chance that a Botbox might release a Hot Wild (Wild with a swirling design around it) when it opens. The Hot Wild releases a random number of Wilds on other symbol positions.
The Multisymbol is a number of symbols stacked on one reel position. The Multiplier symbol adds its value to the multiplier and turns into a Wild symbol. The expand grid symbol (arrow) expands the grid with one column and one row up to a maximum of 7 rows by 7 columns.
For those who cannot wait, Tinkerbot’s X-iter menu allows you to instantly trigger bonus rounds. With options like Bonus Hunt (3x bet), Feature Fest (10x bet), Super Drop (25x bet), Bonus Game (100x bet), and Super Bonus Game (500x bet), you can buy your way to guaranteed feature action, bypassing the randomness of bonus triggers.
The slot game tries to capture every person’s intrinsic love/wish for rummaging through a post-apocalyptic junkyard and finding hidden treasure. I assume that is the case with every person. Despite a below-average 94% RTP, the slot’s quirky cluster-pays mechanics, cascading wins, and unpredictable Botboxes kept me thoroughly entertained. Once I got a hang of the multisymbol explosions and grid expansions, every spin felt like a mini-adventure. Sure, it might not convert hardcore slot veterans, but for those who enjoy a bit of ELK Studios’ creative chaos, Tinkerbot offers a fun, rewarding ride. It can easily be a blast once you learn the ins and outs.
