Hollow Sun Slot Demo by Halostudios

Hollow Sun by Halostudios Slot Overview

Hollow Sun by Halostudios lights up a solar temple with vivid reds, ornate gold and a smiling sun deity. Its Wild multipliers and mystery symbols connect it with The Crypt 2, but here Suns rise into full Wild reels when they contribute to winning paylines.

The Rising Sun feature gives this high-volatility slot its spark: during free spins, risen Suns remain, with multipliers climbing after wins they help form, up to x100. The maximum payout reaches 10,000x the bet. Explore these growing Wild reels in the free demo on BonusTiime.

Hollow Sun Slot Specifications

Hollow Sun uses a 5×4 grid with 20 fixed paylines that are always all active. A win is 3, 4 or 5 matching symbols in a row on a payline, starting from the leftmost reel, only the highest win on each payline counts, and wins on different paylines are added together. The house edge is 3.50%.

RTP (Return to Player)

96.50% RTP gives Hollow Sun a solid return profile. The house edge sits at 3.50%.

Volatility

High volatility means sharper swings, with wins and bonus hits spaced out rather than arriving steadily.

Max Win

10,000x the bet caps Hollow Sun, so a €1 spin reaches €10,000 at the top prize.

Hollow Sun Slot Features

Veils all lift to show one and the same symbol when the reels stop, Sun Wilds land on reels 2 to 5 and substitute for every symbol except the Scatter, Rising Sun turns a qualifying Sun’s whole reel into a Wild reel carrying one multiplier, and Eclipse Free Spins and Total Eclipse Free Spins extend the action with persistent Suns and rising multipliers.

Veil

The Veil can land on any reel, often several times in a column. When the reels stop, every Veil on the board lifts to reveal one and the same symbol, chosen at random from the paytable symbols. It does not pay by itself, and wins only count after the reveal.

Sun Wild

The Sun Wild lands on reels 2 to 5, with at most one on each reel. It substitutes for every symbol except the Scatter, and it never lands on reel 1, so any winning payline always starts with a paytable symbol. That keeps the pattern clear and readable.

Rising Sun

When the reels stop, each Sun Wild is checked for a qualifying win. If its full reel, turned Wild, would be part of at least one winning payline, the Sun rises and turns that reel into a Wild reel on every crossing payline. The reel shows one multiplier, and a payline win is multiplied by the sum of the multipliers of the risen reels it crosses, so x5 and x10 on the same payline make x15. A Sun Wild that would not be part of a win does not rise, and stays one Wild symbol with no multiplier.

Scatter and Eclipse Free Spins

The Eclipse Scatter lands on any reel, with at most one per reel, and it does not pay. Three Scatters award Eclipse Free Spins, while 4 or more award Total Eclipse Free Spins. During free spins, standing Suns stay active, and after each free spin, those that helped create a win step their multiplier up one place on the ladder, to x100 at most, with the increase applying from the next spin. New Sun Wilds and Scatters land only on reels with no standing Sun, and a Sun that rose on the spin that triggered the free spins does not carry into them.

• 3 Scatters: 8 free spins.
• 4 Scatters: 10 free spins.
• 5 Scatters: 12 free spins.
• x2, x3, x5, x10, x15, x25, x50, x100: Rising Sun multiplier ladder.
• 1 free spin: added for each Scatter during free spins.

Buy Bonus

Hollow Sun has three paid modes: one switch that stays on and is paid again on every spin, and two free-spin rounds bought once each from the bonus menu.

• Bonus Chance: x1.25 the bet per spin; Scatters land more often, so free spins trigger on average once in 143 spins instead of once in 286.
• Eclipse Free Spins: x100 the bet; starts with 3 Scatters and 8 free spins.
• Total Eclipse Free Spins: x300 the bet; starts with 4 Scatters and 10 free spins.

Hollow Sun Slot Review

Hollow Sun builds its identity around a bright Egyptian solar court, with a sun deity, ornate gold framing and a temple backdrop that give the reel set a clear, styled look. The presentation works because the artwork supports the Rising Sun idea instead of sitting beside it as decoration.

During free spins, the gameplay stands out most when Wild reels start stacking through Rising Sun, because each qualifying Sun can stay active and lift its multiplier with later wins. That gives the high volatility a real reason to matter, while the buy options add pace without hiding how swingy the base game can be.

Hollow Sun lets risen Suns remain throughout free spins, with their multipliers climbing towards x100 after spins in which they contribute to a win. The 10,000x ceiling is strong, but the game still asks for patience. It lands as a sharp concept with a clear ceiling.
