Scales of Dead is a game from the renowned developer Playn Go. The developers are known for their vast portfolio, and the game continues the Book slot series' familiar gameplay with an added twist to the bonus round. These are some of its features:

- The slot theme and storyline are set in Egypt, presenting you a view of the rich golden sands of the Sahara desert enveloped by pyramids.

- Consistent with the genre, there are 5 reels with 3 rows and 10 win lines, where the symbols create winning combinations from left to right. To achieve a win, you need 3 or more of the low symbols, while the premium symbols traditionally pay from 2-of-a-kind and more.

- A wide array of symbols and paytable is available, including numbers and letters (10, J, Q, K, A), an Ankh, Bird, Cat, and Snake. Each of these has individual payout scales.

Special Features include:

- Tomb Symbols: These are both Wild and Scatter at the same time. Acting as substitutes for any other regular symbols, they help you achieve payouts. When 3 or more instances land simultaneously anywhere in view, they trigger the bonus round, plus, they grant cash prizes.

- Free Spins: When a required combination of tomb symbols appears, players receive 8 free spins. Upon the start, a random regular symbol is chosen and turned into a special expanding symbol. When enough of the respective symbol lands, regardless of whether they are adjacent or not, they expand to cover all reel positions and award a win across all 10 paylines.

- Sandstorm Free Spins: This feature triggers with 4 initial spins when 2 or more tomb symbols land during the standard Scales of Dead free spins. A random multiplier is assigned to the chosen expanding symbol before the feature kicks off. This multiplier can be either 2x, 3x, or 4x.

- Gamble: Whenever you achieve a win during the base game, you can increase the amount via the Gamble feature. You need to guess the color or suit of a random card to double or quadruple the payout, respectively. This feature is repeatable up to five times.

In terms of the game's technical aspects:

- Five different RTP settings are available: 96.21%, 94.21%, 91.21%, 87.21%, and 84.21%.

- The game is highly volatile, with a rating of 9 out of 10 by the developers.

- The max win of 10,000x the bet is available.

The game can be played on a desktop or mobile platform as it's designed with HTML5 technology.
