Further slot guides
Here’s how you enjoy the main game features of Thief slot.
How to play
To get started, select your preferred betting options using the clearly marked controls beneath the reels. Adjust the Coin Value by clicking the left or right arrows on the right side of the Spin button. Choose among denominations such as 0.01, 0.02, 0.05, 0.10, 0.20, or 0.50.
Select your desired Level, located to the left of the Spin button. This sets how many coins will be wagered per line, across all 25 fixed paylines. Levels range from 1 to 10, easily adjustable via arrows.
If you want to maximise your bet for a single spin, simply press the Max Bet button. This moves your wager to the allowed maximum, ranging from 0.25 up to 125 coins.
Once your bets are set, hit the central Spin button (circular arrows) to begin. You can also use the same button to stop the spin early if needed. For hands-free play, the Autoplay button (to the left of Spin) lets the reels operate uninterrupted for a preset number of spins.
RTP and payouts
In Thief, the top achievable win is 68,500 coins when playing at maximum stakes. The game has a return to player (RTP) of 96.7% and sits at a medium to high volatility level. This means the payout frequency strikes a balance between regular smaller wins and the chance for larger prizes, especially during extended sessions.
All 25 paylines are permanently enabled, giving you consistent opportunities to land winning combinations. The paytable is available in-game to show the values for all symbols, allowing you to plan your strategy and monitor potential returns.
Special attention should be given to the free spins features, where you can secure wins of up to 500 times your bet per spin. The female burglar acting as an expanding wild increases your prospects by substituting for standard symbols to complete paylines more frequently.

Special features in Thief slot
The absence of a traditional bonus game is compensated by two engaging free spins rounds. Here’s a breakdown of the game’s standout features.
Symbols explained
Every symbol fits into the digital burglary theme. Low-value icons cover the familiar card ranks 10, J, Q, K, and A, while higher-value symbols showcase heist gadgets like night vision goggles, green lasers, safes, and spy watches. The most lucrative regular symbol, the night vision goggles, pays out 500 times your bet level for five on a line.
The diamond symbol appears exclusively in the Adrenaline Free Spins mode and stands as the ultimate prize, awarding up to 5,000 times your stake when five land on the reels simultaneously.
Wild and scatter symbols
The wild symbol is depicted by the female cat burglar. She can appear expanded over the second, third, and fourth reels during both base and free spins rounds, substituting for other icons except scatters to help form new wins.
There are two types of scatter symbols: a blue tunnel (regular scatter) and an orange tunnel (Adrenaline scatter). These scatter symbols land only on reels 3, 4, and 5. Landing three of any scatter type activates 10 free spins.
