Tanked slot by Nolimit City

Tanked slot machine overview

Tanked is a Nolimit City slot built around movement rather than reels. Four characters, each driving a tank, sit on a grid of coloured gems. On every drop they collect matching gems within reach, the gaps refill from above, and the grid grows as explosions knock its walls outwards. The full-size board is 9 × 9.

It belongs to the same family of ‘collector’ games as ELK Studios’ Pirots, where birds gather gems on a grid slot machine layout. Tanked adds Nolimit City’s own toolkit on top: nudging wilds, splitting symbols and bombs, plus a three-tier free spins structure. The cartoon armour theme is aimed at adult players; like every real-money slot, it is for over-18s only.

How a Tanked spin plays out, step by step

The order of events is worth knowing, because it explains why a single paid spin can run for a long time on screen. Everything you see is the playback of an outcome the game server settled when you pressed spin.

1. Pick a stake. UK casinos cap it at £2 a spin for 18–24s and £5 for players aged 25 and over.
2. Press spin. The random number generator fixes the full result, including every drop and explosion.
3. Gems fill the grid and each tank collects the matching gems it can reach, paying their values.
4. Collected gems vanish and new ones drop in, as with cascading reels, so collecting can continue.
5. Special symbols and boosters fire when the tanks get stuck, clearing space and sometimes expanding the grid.
6. When nothing more can be collected, the total is paid and your balance and net position update.

The sequence must take at least 2.5 seconds under UK rules, and there is no button to skip it. Many Tanked spins are short, ending after a single collection; the long chains are the exception.

Tanks, gems and how wins are paid

There are no paylines or ways. Each character is linked to a gem colour, and published descriptions say it collects matching gems within adjacent reach, with each collected gem paying a small fraction of the stake. Wilds can be picked up by any character. That makes Tanked pay like a running tally: lots of small amounts added together, then raised by any multiplier in play.

A worked collection

Take an illustrative case at a 50p stake. One tank collects six gems worth 0.1× stake each (30p), another collects four worth 0.15× (30p), and a 3× multiplier is active. The sequence pays (30p + 30p) × 3 = £1.80. Gem values here are invented for the arithmetic; the real values are in the game’s paytable and change with your stake.

Published descriptions also say each character has a set number of lives, and that tanks colliding can set off ‘booms’ that clear gems and, in the larger case, push the grid out a step. Those rules decide how far a sequence can run, so they are worth reading in the help screen before playing for money.

xNudge, xSplit, xBomb and the tank boosters

Tanked uses three of Nolimit City’s signature symbols. The descriptions below come from published game sheets and are simplified; the in-game rules are the reference.

You can read more about each idea on our pages for XNudge, split symbols and expanding reels. The xBomb is also the namesake of Nolimit City’s Fire in the Hole xBomb, a mining-themed game with a 60,000× cap.

Multipliers in Tanked add together rather than multiply each other, according to published descriptions. Two separate +2 boosts make a larger multiplier, not a squared one. Check the help screen for the starting value.

Tanked free spins: Carnage Spins and the upgrades

The main Tanked bonus is Carnage Spins, a free spins round triggered by scatter symbols. Its key feature, confirmed in our checked data, is that the multiplier and grid size you have built in the base game carry into the round rather than resetting. A spin that enters the feature with a big grid and a high multiplier is starting from a much stronger position.

Published descriptions name two stronger tiers. Carnage Royale, from a higher scatter count, is described as starting on the full 9 × 9 grid with an added multiplier boost. Mayhem Spins is described as an upgrade reached when all four tanks are destroyed in the same explosion, again with a raised multiplier. Multipliers are said not to reset between these tiers. Scatter counts and spin totals are in the game’s help screen.

This tiered design is a large part of why the game is high volatility. Most bonuses will be standard Carnage Spins, and many will pay less than you might expect; the upgraded tiers are where the extreme results sit. Our pages on progressive multipliers and what triggers a bonus round explain the general mechanics.

Tanked RTP and the cost of play

The best published Tanked RTP is 96.04%, and lower versions exist. The casino decides which tested setting it runs, so the number you get is in the help screen, not on a review site. Our explainer on slot RTP covers why RTP is a long-run figure.

Those averages hide how a high-volatility game feels in practice. With a £50 budget at 50p a spin, it is entirely normal for the money to run out in fewer than 100 spins without a bonus, because a large share of the 96.04% is paid back through rare, big sequences. Our guide on how long money lasts on slots works through examples like this.

Tanked max win at UK stake limits

The Tanked max win is 25,000 times the stake. If a sequence reaches it, the game stops and pays the capped amount. That ceiling is high compared with many mainstream slots, though below some of Nolimit City’s own extreme titles.

The cap is the edge of the maths model, not a target. No hit rate for it is confirmed in our checked data, and it is reached on a vanishingly small share of spins. Our max win caps page explains how caps are applied, and what slot has the biggest max win puts 25,000× in context.

How high volatility shapes a Tanked session

Volatility describes how a slot spreads its return. A high-volatility game like Tanked pays a lot of small amounts and a few very large ones, with long stretches in between. The volatility explainer and the page on standard deviation go into the maths.

• Expect many spins that return nothing or a fraction of the stake.
• Budgets can fall faster than the RTP table suggests before a feature lands.
• A single bonus can account for most of a session’s return, or very little.
• Smaller stakes give a budget more spins, but don’t change the odds per spin.

If you prefer steadier play, a lower-volatility game will usually suit better; see high vs low volatility slots for the comparison.

UK rules that apply to the Tanked slot

Tanked versions supplied to Great Britain follow the Gambling Commission’s online design rules, in force since 31 October 2021 and set out in the Commission’s RTS 14 responsible product design standard (opens in a new tab).

• No autoplay; each spin is started by hand.
• Spins last at least 2.5 seconds, with no turbo or quick stop. See the 2.5 second spin rule.
• A return equal to or below the stake isn’t celebrated as a win; the losses disguised as wins rule explains why.
• Balance and net position stay visible.
• No bonus buy: the paid entry options listed in reviews for other markets aren’t offered to UK players.

Stake limits are applied by the casino to your account: £5 a spin for those aged 25 and over since 9 April 2025, and £2 for 18–24s since 21 May 2025. The Gambling Commission’s stake limit guidance (opens in a new tab) has the official wording.

Tanked demo and how to check the RTP

A Tanked demo, where a UK casino offers one, is free demo play after age verification; operators have had to confirm players are 18 or over before any free-to-play game since May 2019. Under the Commission’s play-for-free standard (RTS 6) (opens in a new tab), a demo must reflect the real game, so it is a fair place to learn the tank and booster rules.

1. Load the game and open the information menu.
2. Find the theoretical RTP; 96.04% is the top published setting.
3. Read the sections on lives, booms and grid expansion.
4. Check the scatter counts for Carnage Spins and the upgraded tiers.
5. Confirm the 25,000× max win statement and the stake range.

Tanked vs Pirots, and three myths

On the published figures, Tanked has a larger maximum grid, a higher top RTP and a higher cap than Pirots 2. Collect mechanics look similar, but the pay rules, multipliers and bonuses differ, so they aren’t interchangeable.

Three beliefs come up often. First, that a grid left large after a spin means the next spin is promising: online, each spin starts from its own random result. Second, that the tanks ‘aim’ well or badly depending on recent wins: their moves are part of the fixed outcome. Third, that a dry run makes Carnage Spins due: no slot keeps a debt. Our guide to slot machine myths explains these errors in more depth.
