Cthulhu 2 by Lotors Slot Overview
Cthulhu 2 by Lotors brings cosmic horror to life with cartoon tentacles, glowing machinery and neon-purple scenery. Its Cluster Pays mechanic connects it with Golden Boy, but here tentacle-driven cell upgrades and persistent bonus marks give the alien setting a distinctive gameplay identity.
Tentacle Strikes upgrade cells up to x20, while marks remain throughout Free Spins. Red Alert, Awakening and Zero Hour add distinct bonus conditions to this high-volatility slot, with a maximum win of 15,000x the bet. Explore these features in the free demo on BonusTiime.

Cthulhu 2 Slot Features

Tentacle Strikes, Free Spins, Portal, Wild Column and Boarding drive Cthulhu 2’s feature set, mixing cell upgrades, persistent marks, bonus entry and moving wild columns across its online slot gameplay.
Tentacle Strikes
Tentacle Strikes are guaranteed by Tentacle, Double Power and Void Wrath symbols. These symbols guarantee at least 1, 2 or 3 strikes respectively in the spin; only the strongest applies, and the values do not add. The rules also say these special symbols do not form clusters, so they work as a separate feature rather than a standard win symbol.
Portal
Portal acts as the scatter-style bonus trigger. Three, four or five or more Portals at the end of a base spin open Red Alert, Awakening or Zero Hour. The feature does not form clusters, so its value comes from starting the bonus rather than paying as part of a cluster.
Wild Column
Wild Column can rise in whole columns on any base spin, and it also appears in Free Spins. One wild column substitutes for every paying symbol in one calculation. In Sticky Wild form, it remains in place and jumps to another column every spin, which keeps the feature active across the bonus.
Free Spins
Free Spins start when three, four or five or more Portals land at the end of a base spin. The game awards 10 spins through Red Alert, Awakening or Zero Hour. Marks stay on the board for the whole bonus, and in Zero Hour every cell starts at x2 for stronger board growth.
During Free Spins, each Portal adds spins whether it lands with the new board or arrives through a cascade. One Portal adds 1 spin, two Portals add 2 spins, and three or more add 4 spins in one spin.
- Red Alert: 10 spins, 1 to 3 Tentacle Strikes per spin.
- Awakening: 10 spins, 2 to 3 Tentacle Strikes per spin.
- Zero Hour: 10 spins, 3 Tentacle Strikes per spin, with x2 cells.
Boarding
Boarding starts when 3 Torn Airlocks land on the base board. The rules say Airlocks do not form clusters, so they exist as a distinct bonus trigger rather than a normal paying symbol. This mode sits alongside the other features and gives the game another route into bonus play.
Buy Features
Every card in the Buy Feature menu is a mode: once chosen, it plays every spin at its price until it is switched off.
- Void Signal: x3 the bet per spin; base spins in which the Old One can still rise as a Wild Column.
- Void Strike: x10 the bet per spin; 1 to 3 Tentacle Strikes every spin, no Portals, wins capped at 68.6x the bet.
- Red Alert: x100 the bet per spin; 10 free spins with 1 to 3 Tentacle Strikes each, all marks stay.
- Boarding: x100 the bet per spin; starts the Boarding feature, capped at 1,006.5x the bet.
- Awakening: x200 the bet per spin; 10 free spins with 2 to 3 Tentacle Strikes each, all marks stay.
- Sticky Wild: x375 the bet per spin; 10 free spins in which the Wild Column stays and jumps to another column every spin.
- Zero Hour: x1,000 the bet per spin; 10 free spins with 3 Tentacle Strikes each and every cell starting at x2.

Cthulhu 2 Slot Review
Cthulhu 2 builds its identity around a bright, cartoonish cosmic horror look, with neon purples, green accents and a board full of tentacles, portals and eye symbols. The theme works because the art is not just decoration; it supports the bonus names, the wild columns and the cell upgrades on the board.
The main strength sits in the cluster structure and the layered bonus design. Tentacle Strikes can upgrade cells up to x20, while Free Spins keep marks in place and add spins through Portals. That gives the slot more going on than a standard cluster game, although the high volatility keeps the experience demanding.
Cthulhu 2 suits players who want a themed slot with real bonus depth and a clear ceiling of 15,000x the bet. It will appeal most to bonus hunters and high volatility players, while anyone wanting frequent small returns may find the swings too sharp.
Cthulhu 2 Slot FAQ
How Do Free Spins Trigger In Cthulhu 2?
Free Spins trigger when 3, 4, or 5 or more Portals land at the end of a base spin. The game opens Red Alert, Awakening, or Zero Hour, each with 10 spins. Portals do not form clusters, so they act as a bonus trigger rather than a paying symbol.
What Do The Buy Options Cost And Give?
The Buy Feature menu holds seven modes, each charged on every spin until it is switched off. Void Signal costs x3 the bet per spin, Void Strike x10 the bet per spin for 1 to 3 Tentacle Strikes every spin, Red Alert x100 the bet per spin for 10 free spins with 1 to 3 strikes, Boarding x100 the bet per spin, Awakening x200 the bet per spin for 10 free spins with 2 to 3 strikes, Sticky Wild x375 the bet per spin for 10 free spins with a jumping Wild Column, and Zero Hour x1,000 the bet per spin for 10 free spins with 3 strikes and every cell starting at x2.
What Is The Max Win In Cthulhu 2?
Max Win reaches 15,000x the bet in Cthulhu 2. The rules say the round ends once that limit is reached, and the maximum win is paid. That cap applies to the overall game, while Void Strike and Boarding have lower limits in their own modes.
Can You Play Cthulhu 2 For Free?
Yes, Cthulhu 2 is playable for free on this BonusTiime page, with no deposit or account needed. The demo gives you a way to test the online slot gameplay before playing the full version. It is the same game, just without real money pressure.
How Does The Signature Cluster Mechanic Work?
Cthulhu 2 uses Cluster Pays, not fixed paylines. Wins pay for clusters of 5 or more matching symbols, and larger clusters pay more. The paytable shows values for cluster sizes from 5 up to 16, so the board rewards grouped matches rather than line-based combinations.
