How to Play 4 Stones

Getting started with 4 Stones is incredibly simple, making it accessible for both newcomers and seasoned slot enthusiasts. The game uses a 5-reel, 3-row layout with 81 fixed paylines, meaning wins are formed by landing matching symbols on adjacent reels starting from the leftmost reel. Players can adjust their total bet using the coin value and bet level controls, with a betting range accommodating everyone from casual players to high rollers, starting at a minimum of 0.1 and going up to 40 per spin. Key controls are clearly marked: simply set your desired bet, hit the spin button to start the reels, or use the autoplay function for a set number of consecutive spins. The paytable, accessible via the menu button, details the value of each symbol, helping you understand what to look for on the grid.

Symbols, Paylines & Payouts

The symbol set in 4 Stones is elegantly simple. The lower-paying symbols are represented by classic card suits—spades, hearts, diamonds, and clubs—stylized in a modern, gem-like fashion. The higher-value symbols are the four beautiful gemstones themselves: a purple amethyst, a green emerald, a red ruby, and a blue sapphire. The most lucrative of these is the blue stone, which pays out the highest for a five-of-a-kind combination. There is no traditional wild symbol in this base game, which is an interesting design choice that keeps the focus squarely on the stone symbols and the special features they can trigger. The 81 ways-to-win system ensures there are ample opportunities for winning combinations to land on every spin.

Bonus Features & Special Mechanics

While 4 Stones may appear minimalist, it packs a punch with its engaging bonus features centered around its namesake symbols.

• Stone Collection & Free Spins: The core bonus mechanic involves collecting the four colored stone symbols. Each time a stone lands on the reels, it is collected in a meter on the side of the grid. Once you collect all four different stones, you are rewarded with an initial batch of free spins.


• Progressive Free Spins Feature: The excitement doesn't stop there. During the free spins round, the stone collection mechanic remains active. Every new set of four distinct stones you collect during the bonus will retrigger and award additional free spins. This progressive element can lead to extended play and significantly boosted win potential within the feature.


• Feature Multipliers: To further enhance wins during the free spins, collecting stones can also award random multipliers. These multipliers are applied to your wins, creating the potential for some impressive payouts during the bonus round.

Volatility, RTP & Betting Range

4 Stones is classified as a medium volatility slot. This means it strikes a balance between the frequency of wins and the size of payouts, offering a gameplay experience that is neither too relentless nor too sporadic. It's an excellent choice for players who enjoy steady action with the chance for moderate to sizable wins. The betting range is notably flexible, starting at just 0.1 and scaling up to 40 per spin. This wide range makes the game perfect for bankrolls of all sizes, allowing for careful budget management or more significant stakes for those seeking bigger thrills.
