Crystal Sun is a five-reel, ten-payline game where lines pay in both directions and the central feature is an Expanding Wild that can carry several multiplier values. Its Wilds occupy reels two through four, expand when they land, and initiate respins that last only while more Wilds continue to appear.

| Main features | The game has 10 fixed paylines, but these aren’t your usual paylines…they run both ways! That’s right if you match 3, 4 or 5 symbols from left to right OR right to left you can grab yourself a win. As always, the game’s Wild symbol can stand in for any other symbol to help create winning combinations, but this is no ordinary Wild, it’s THREE Wilds in one! The Expanding Wild has x1, x2 and x3 multipliers that may appear when it lands. For Crystal Sun, the checked rules leave the next outcome independent after the main trigger. A visible setup can therefore continue, improve or end without guaranteeing a higher return. The practical boundary in Crystal Sun is the end of its named feature state. Once that state closes, retained values and temporary modifiers no longer describe the following base-game result. |

How the regular game is read
A normal win can run left to right or right to left across the ten fixed paylines. The Wild substitutes for other symbols, but its placement is deliberately restricted to reels two, three and four. This makes it useful in the middle of a line yet unable to repair every possible gap at either edge of the reel set.
The documented feature route
When an Expanding Wild lands, it always expands and awards a respin. It may carry x1, x2 or x3, and qualifying multiplier values on winning paylines are added together. Respins continue until no more Wilds land. The addition rule applies to Wild multipliers on a successful line; it is not a blanket multiplier for all symbols visible during the feature.
What carries forward — and what does not
The duration has a plainly stated stop condition. A first Wild begins the respin sequence, but the next respin must supply another Wild to continue it. Multiple values can combine on a line, though the restrictive middle-reel positions still shape which lines can benefit. A board with an expanded Wild can look promising and nevertheless end the sequence immediately if no fresh Wild arrives.
Recorded configuration for this version
The official record for this exact standard version lists 96.6% RTP, 6/10 volatility and a maximum win of 4000x. Its release date is 2019-04-24. These values describe the saved configuration, not the likely outcome of a session or a feature. Where a site offers alternative approved RTP settings, the live information panel remains the appropriate final check before play.
Strengths and weak points
Strengths
The strength is mechanical rather than cosmetic: When an Expanding Wild lands, it always expands and awards a respin This gives the player a concrete rule to follow when the feature state appears.
Weaknesses
The drawback is conditional progress: The duration has a plainly stated stop condition. A first Wild begins the respin sequence, but the next respin must supply another Wild to continue it A promising display can therefore end or miss before the intended state is completed.
Our Editor’s View
Crystal Sun rewards readers who like a mechanical link between a Wild’s arrival, its expansion and the next respin. Bidirectional paylines keep the base game less conventional, while added multipliers give consecutive Wild landings an understandable purpose. The trade-off is short-lived potential: the respins stop on the first spin without a new Wild, and even several expanded Wilds must align with a paying line. The 4,000x maximum is not a predicted multiplier combination. Middle-reel placement also restricts which bidirectional lines can receive the expanding Wild. the original Reactoonz review
