Wild Tomb Slot Review: Discovering a Trove of Features 

Thanks to pop culture, Ancient Egypt has been portrayed as supernatural and creepy, which is exactly what Games Global and Alchemy Gaming have leaned into when designing the Wild Tomb slot.

This title, played on PokerStars, uses a 6-reel, 4-row layout with 20 fixed paylines, high volatility and bonus rounds built around Sticky Wilds, sarcophagus upgrades, orb overlay tokens, Free Spins, Super Free Spins and Wild Tomb Mode. At first glance, it looks like a regular Ancient Egypt themed slot, with tomb walls, relics, treasure symbols, mummies, glowing orbs and Wilds. But underneath that, Wild Tomb has a lot more for the player to discover.

Theme and Design: Enter the Supernatural Tomb

The symbol set of this slot game keeps close to the theme. There are mummy and pharaoh symbols, treasure chests, golden urns and relics. The orb overlay tokens add a little more colour to the grid, with green, orange and blue glowing tokens linked to the sarcophagus system. The darker background helps the special symbols stand out, while the chest and sarcophagus unlocks help show players any progression.

The music also suits the slot well, with a mysterious score that feels like it belongs in a desert film scene. Traditional Egyptian-style string and wind instruments give it a more cinematic sound, adding to the atmosphere of the forgotten tomb.

Core Gameplay: Wild Focus and Progressive Unlocks 

Wild Tomb is a 6-reel, 4-row slot game with 20 fixed paylines and wins paying from left to right. A payline win is awarded when matching symbols land next to each other on a payline, and only the highest win is paid per line. That gives the base game a more traditional feel. The grid is larger than a standard 5×3 online slot, but it’s still built around fixed paylines rather than clusters, ways, or cascading wins. The total payout from a spin is all payline wins added together.

Wild Symbols and Sticky Wilds

The Wild can substitute for all symbols except Scatter and orb overlay symbols, helping complete winning combinations across the paylines. Wild symbols can also create their own winning combinations when they land in a payline combination. The Wild and Sticky Wild pay the same values, with 6 symbols paying £6.00, 5 paying £3.00, 4 paying £2.00, and 3 paying £1.00 (based on a £1.00 bet). Sticky Wilds are Wild symbols that stay in place until the mode or bonus round ends. They only land in Sticky Wild Mode, Free Spins and Wild Tomb Mode. Once Wilds can stay on the grid, they can start filling more spots across the remaining spins.

If a Wild lands on a Sticky Wild, it becomes a 2x Sticky Wild multiplier. The multiplier increases by 1 each time another Wild lands in the same reel position. These multipliers only add to line wins they are part of, so their value depends on where they sit and how they connect to the winning lines. This is what makes the Wilds different to other standard online slots, doing more than just substituting.

Chest Unlocks and Sarcophagus

One of the main things that makes Wild Tomb stand out from a more straightforward slot game is the chest unlock system. There are 3 chests that can be unlocked through base game spins, and they reveal more of the slot over time. The first chest unlocks the Expanding Wilds sarcophagus after 50 base game spins. The second chest unlocks the Duplicating Wilds sarcophagus after a further 100 base game spins. The third chest allows Super Scatter symbols to land on the reels after another 100 base game spins.

The Multiplier Wilds sarcophagus is available straight away, which means the game begins with one Wild upgrade already in play, before the other sarcophagus and Super Scatters become available. A sarcophagus can randomly trigger and convert up to 2 Wild symbols into special Wild symbols per spin. Only one sarcophagus can activate on a single spin. The three special Wild types are Multiplier Wilds, Expanding Wilds and Duplicating Wilds. Multiplier Wilds can carry 2x, 3x or 5x multipliers. Expanding Wilds grow to cover the entire reel, turning every spot on that reel into a Wild. Duplicating Wilds add 2, 3, 4 or 5 extra Wilds to random reel positions. If a Wild symbol is expanded over or duplicated onto, it becomes a 2x Wild multiplier. The multiplier then increases by 1 for each extra Wild symbol that lands in that same reel position. This gives the special Wilds a more layered feel, because one part of the game can feed into another.

Orb Overlay Tokens and Sticky Wild Mode

Orb overlay tokens only show up during the base game. They sit over reel symbols and are removed when collected, revealing the symbol underneath. Only one orb overlay token can land on reel 6 per spin. When one is collected, it can increase the Sticky Wild Mode collect counter by 1. A maximum of 5 Sticky Wilds can be collected, and that number is then added to random reel positions on the first spin of Sticky Wild Mode.

A collected orb overlay token can also randomly trigger Sticky Wild Mode. If that happens, the orb token decides which sarcophagus will trigger during the mode. An orb overlay token can also do nothing at all, meaning that they are not always a guaranteed route into Sticky Wild Mode. Orb tokens are linked to the connected sarcophagus, so they can only land for the ones that have already opened.

Sticky Wild Mode lasts for 5 paid spins. Any Wild that lands, or is added to the reels, becomes Sticky. Up to 5 Sticky Wilds are added to random reel positions on the first spin, and 1 or 2 Sticky Wilds are guaranteed to change into special Sticky Wilds on that first spin. Up to 2 new Sticky Wilds can be changed into special Sticky Wilds on each spin. If a Wild lands on a Sticky Wild, it becomes a 2x Sticky Wild multiplier and the multiplier increases by 1 for each extra Wild that lands in the same position.

Feature Upgrade Trail

The Feature Upgrade Trail gives Wild Tomb another base-game build-up route. Landing 1, 2 or 3 Scatter symbols in the base game adds that number of Scatter symbols to the trail. When the trail reaches the right level, the next Free Spins or Super Free Spins round starts with a set number of Sticky Wilds added to random reel positions. Unless a higher level is reached, 5 Sticky Wilds are added when Free Spins begin. 

At 50 collected Scatter symbols, the round starts with 6 Sticky Wilds. At 100, it starts with 7. At 150, it starts with 8. Once the trail is full, no more Scatter symbols can be added to it and triggering Free Spins resets the trail. This gives Wild Tomb a more progressive style than a slot game where the bonus always starts at exactly the same level. The Feature Upgrade Trail means the base game can improve the starting setup of the next Free Spins round, even when 1, 2 or 3 Scatters land without triggering the bonus.

Free Spins and Super Free Spins

Free Spins are triggered by landing 4 Scatter symbols in the base game. This awards 8 Free Spins. If 1 of the 4 triggering Scatter symbols is a Super Scatter, Super Free Spins are triggered instead, awarding 12 Free Spins. Scatters and Super Scatters only land in the base game and don’t have their own payout. Only 1 Scatter can land per reel, and only 1 Super Scatter can land per spin. Super Scatters only land in the base game once chest 3 has been unlocked. During Free Spins, every Wild that lands becomes sticky. If the Feature Upgrade Trail has reached a level for 5, 6, 7 or 8 Sticky Wilds, the round begins with that number of Sticky Wilds added to random reel positions.

Only the sarcophagus that were available in the base game during the trigger are available during Free Spins. That means the bonus can feel different depending on how far the player has reached with the chest unlock system. On the first spin, 1 or 2 Sticky Wilds are guaranteed to change into special Sticky Wilds. Up to 2 new Sticky Wilds can then be changed into special Sticky Wilds on each spin. If a Wild lands on a Sticky Wild, it becomes a 2x Sticky Wild multiplier, with the multiplier rising by 1 for each extra Wild landing in the same spot.

Wild Tomb Mode

Wild Tomb Mode can trigger during Free Spins or Super Free Spins. Wilds that land on, or are added to, new reel positions fill the Wild Tomb Mode meter. Once 12 new Wild positions have been collected, the mode begins. When Wild Tomb Mode is triggered, it gives the player 4 extra Free Spins and adds 4 Sticky Wilds to random reel positions. This mode acts like a second layer inside the bonus round. Free Spins are already built around Sticky Wilds, Wild upgrades and multipliers, but Wild Tomb Mode adds another burst of Sticky Wilds once enough Wild spots have been collected.

Upsizer Feature

The Upsizer feature is offered to players after Free Spins are activated and allows the Super Free Spins round to be triggered at an optional extra bet amount. The Upsizer isn’t available if the Super Free Spins chest is locked or if Super Free Spins have already been triggered. The RTP of this feature stays at 94.00%, so it doesn’t guarantee better results, so it should always be considered an optional extra.

Final Verdict: Wilds Take Over the Tomb

Wild Tomb is a bonus-led PokerStars online slot with a strong, supernatural Egyptian theme. The 6×4 grid and 20 fixed paylines keep the basic setup easy to follow, while the chest unlocks, sarcophagus and orb overlay tokens give the base game more room to build on.

This online slot works best when the Wilds start feeding into each other. Multiplier Wilds, Expanding Wilds and Duplicating Wilds all connect into the same system, while Sticky Wild Mode, Free Spins and Super Free Spins keep the focus on Wilds that can stay on the reels. With its layered features and gradual unlocks, the mechanics of Wild Tomb fit the theme, making the experience feel like exploring an Ancient Egyptian tomb room by room. Each section opens up more of the game, from sarcophagus and Sticky Wilds to the bonus rounds.
