Secrets of Papyrus Slot by Mascot Gaming

Secrets of Papyrus by Mascot Gaming places you in a private scholar's library deep within ancient Egypt. Not the typical pyramid tombs and pharaoh's chambers - this game puts you among dusty shelves lined with rolled papyrus scrolls, golden ink pots adorned with white feathers, magical hourglasses tracking celestial time, and a watchful gilded cat statue standing sentinel in the corner. A quieter, more contemplative kind of Egyptian slot. Released January 21, 2026, the game runs on a 5-reel, 4-row grid with 20 fixed paylines, high volatility, 95.89% RTP, and a maximum win of 2000x your stake.

The Symbol Set

Eleven regular paying symbols tell the library's story. At the top sits a luminous blue crystalline medallion - an ancient seal etched with the Eye of Horus - awarding 5000x the line bet for five across. Below it, a papyrus scroll drawn with pyramids and celestial maps pays 2000x for five. Ink pots topped with white quill feathers (1000x), glowing hourglasses filled with blue sand (600x), a gold-capped scroll tube sealed in red wax (400x), and smaller coin pendants round out the premium tier (200x). The lower half belongs to A, K, Q, J, and 10 symbols in ornate Egyptian gold script, ranging from 50x to 130x for five of a kind.

Then there's the Mystery symbol - an Egyptian figure, bald, draped in ceremonial robes, clutching a golden key. It glows with an amber aura when it lands. This symbol is both the scatter and the Mystery mechanic's engine: when Mystery symbols land, they immediately transform into one of the regular paying symbols chosen at random. When multiple Mystery symbols land simultaneously, they all transform into the same symbol. Two Mysteries on a payline becomes two matching symbols. Three becomes a three-of-a-kind from the scatter trigger alone.

Mystery Symbols in the Base Game

The Mystery symbol appears exclusively on reels 2, 3, and 4 - the central section of the grid. Reels 1 and 5 carry only standard symbols, which keeps the transformation mechanic focused where it matters most. The random reveal happens before payout calculations, so you always see exactly what you won before the win counter fires. Clean implementation without confusion.

Free Spins Bonus

Land three Mystery symbols anywhere on reels 2, 3, or 4 to trigger 10 free spins. The bonus round fundamentally changes how Mystery symbols behave. Instead of transforming and leaving, every Mystery symbol that lands becomes sticky - it locks in place and stays for the entire duration of the free spins sequence. Each sticky Mystery still reveals a random symbol, and that revealed symbol holds for all subsequent spins while it remains locked.

This creates a compelling progression. Early free spins might feature one or two locked positions. By spin six or seven, the central reels can be substantially covered, funneling every spin through a densely packed symbol arrangement that amplifies winning combinations. You can physically watch the bonus building as sticky Mysteries accumulate.

The maximum expression of this mechanic is a full cover: all 12 positions on reels 2, 3, and 4 locked by sticky Mystery symbols, each showing the same high-value symbol. When that happens, the game awards 3 additional free spins - enough to realize the full potential of a locked grid where every payline crosses through three or more matching premium symbols.

Boost Feature

The Boost button doubles your bet for a configurable number of spins. What it delivers is an increased rate of Mystery symbol appearances during base game play, making the three-scatter trigger noticeably more frequent. A middle ground between standard play and the Buy Feature - letting you chase the bonus without committing to a full 100x cost.

Buy Feature Options

Two buy-in options sit in the bottom right corner. The Buy Feature costs 100x your total bet and delivers 10 free spins immediately, bypassing the scatter mechanic entirely. At minimum bet of €0.20, that's €20 for a guaranteed bonus entry. The second option - Buy Free Rounds - costs 75x your bet for 25 free spins. More spins, lower cost per spin, and a longer window for sticky Mystery symbols to accumulate across the central reels.

Risk Wheel

Any base game win can optionally be taken to the Risk Wheel, where three risk tiers let you gamble your win for multiplied returns up to a maximum of 1000x. Win big or lose everything. Entirely optional and capped at a defined maximum, so even risk-averse players can engage without unlimited downside exposure.
