Eclipse Princess: Slot Overview
Eclipse Princess pitches a full moon and delivers a keyhole. Set for release on 15 December 2026, Hacksaw Gaming‘s cluster slot plays out across 6 reels and 6 rows as a serene, nocturnal ballet about twin sisters Diana and Amaya, who awaken the powers of the moon on the way to the treasures of the Lunar Palace. Under an indigo sky, the translucent navy grid is flanked on the left by a pale castle of spires and crescents, and on the right by the dark-haired twin floating in a strapless midnight tutu, complete with silver wing clips in her hair, a moon-phase tattoo across her thigh, and ballet ribbons laced down to her pointe shoes. It is a crisp, modern 2D anime presentation that blends the lunar aristocracy of Sailor Moon with the twin-swan mysticism of Swan Lake and Princess Tutu. Built on medium volatility with a default RTP of 96.30% (alongside lower operator settings of 94%, 92%, and 86%) and a 0.10 to 200.00 bet range, the math trades Hacksaw’s ferocious top-end spikes for a tighter geometry game where the exact four cells a cluster touches matter far more than how large it grows.
Eclipse Princess: Slot Features
Yet what the splash screen advertises, an enlarged roaming multiplier frame and birdcage Wild Boosters, isn’t what the base game or the standard bonus actually hands over. The entry-level free spins keep the Lunar Zone frame at 2×2 and lock the Wild Boosters out of the reel strips altogether, saving the full toolkit for a 200x super-bonus buy.
There is no progressive or fixed jackpot attached, and the win cap tops out at 5,000x the bet. While the studio does not publish the exact probability of hitting that ceiling, the rules make the 5,000x max win reachable in every mode, including the base game, all three FeatureSpins modes, and both bonus rounds. The moment a round reaches 5,000x, it ends immediately and any remaining cascades or free spins are discarded.
Despite the ornate character art flanking the frame, the 36-tile board itself looks somewhat austere because four of the five low symbols (an orange octagon, a purple diamond, a green triangle, and a blue drop), plus a star-veined blue orb, sit inside nearly identical round silver bezels. All five share a single paytable line, starting at 0.1x the bet for a five-symbol cluster and topping out at 10x for 15 or more. Above them sit two matched pairs of premiums: emerald pointe slippers and a crescent-stoppered potion vial paying 0.3x to 25x, followed by a silver hourglass and a moon-bow harp paying 0.4x to 40x. The gold tiara leads the table at 0.5x for five up to 50x for 15+, paying five times a low symbol at every cluster size. Feathered Wild symbols also drop in to substitute for any regular paying icon, though a Wild pays nothing on its own and carries no internal multiplier, so all multiplier action comes strictly through the Lunar Zone.
A 34.97% hit frequency keeps the grid moving on roughly one spin in three, but raw five-to-nine-symbol clusters barely return a fraction of the stake. Every paying symbol hides a steep cliff between the 8-9 and 10-11 size brackets: the tiara and all five lows jump fourfold across that gap (0.5x to 2x on a low; 2.5x to 10x on the tiara), while the other four high symbols jump fivefold, taking the hourglass from 1.5x to 7.5x. Below 10 connected tiles, every low cluster and the first three tiers of every high symbol except the tiara pay less than 1x the bet. Without help from the center of the board, ordinary cascades slowly whittle a balance down in fractional rebates.
The 2×2 Lunar Zone and Super Cascades
To bridge that paytable cliff, Hacksaw pulls all the action toward the middle of the screen through three linked mechanics:
- Super Cascades: Whenever a winning cluster lands, the game wipes every regular symbol of that matching type from the entire 6×6 grid, not just the connected win, before new tiles drop in. Clearing out dead low-value bezels from the outer corners gives the central multiplier box fresh drops on the same spin.
- The Lunar Zone: Anchored as a 2×2 square over the four central cells (rows 3-4, columns 3-4), this positional frame starts at 2x and climbs by +1x on every cascade before resetting between base spins. The real hook is how it compounds: before boosting a payout, the zone’s multiplier is multiplied by the number of the winning cluster’s own symbols sitting inside those four central cells. A five-symbol low cluster worth 0.1x pays 0.2x with one tile inside a fresh 2x box, 0.8x when four of its tiles fill the box, and takes a 6x boost when two tiles catch a 3x frame. By contrast, sprawling clusters out on the perimeter collect flat paytable scraps.
- Full Moon Expansion: If a Full Moon symbol lands inside the four cells of the Lunar Zone, it turns Wild, bathes the screen in a violet eclipse, and stretches the Lunar Zone across all 36 positions on the board for the rest of the spin. Because every tile in every winning cluster now counts as sitting inside the frame, a 10-symbol cluster under a 5x expanded zone receives a 50x multiplier, the lone base-game engine capable of erasing a cold run or pushing all the way to the 5,000x cap.
Winged cameos and reel strip lockouts
Triggering free spins requires three or four FS scatters landing at the same time to launch Brightside Blessing (3 scatters) or Darkside Destiny (4 scatters), each awarding 10 free spins. Once the reels settle, the scatter drops its bold "FS" lettering and reveals a circular cameo portrait of the dark-haired princess framed by white wings extending past the cell border.
Two layers of mechanical friction stand between the base game and those portraits. First, the internal reel rules enforce a strict mutual exclusion: FS scatters and Night Bloom multiplier flowers cannot land on the same spin as a Full Moon or during an expanded Lunar Zone. Whenever the base game delivers its full-screen purple eclipse, a bonus trigger is mathematically locked out for that round. Second, once a bonus is underway, the scatter weight tightens from 1.87 per 100 cells in the base game to 1.33 on the free spins strips, and landing a portrait only adds +1 extra free spin (with up to three scatters able to land at once) when it drops directly inside the Lunar Zone.
Brightside Blessing (60x) vs. Darkside Destiny (200x)
Entering either bonus shifts the underlying reel strips noticeably in the player’s favor while removing the Full Moon symbol completely (0.03 per 100 cells in the base game, zero in the bonuses). Across every 100 cells, the top-paying Tiara climbs from 5.88 to 7.91, the Crescent vial rises from 6.30 to 8.33, and feathered Wilds jump from 0.90 to 1.51, while the five low-paying gems fall slightly, with the Purple Gem dropping from 13.18 to 10.21.
Brightside Blessing (60x the bet on the buy menu, 96.35% RTP) swaps both the stage and the heroine. Ironically for a feature called "Brightside," the pale castle vanishes into a dark night sky hung with giant silver birdcages over a carpet of glowing petals, while the melancholic dark-haired sister is replaced by her smiling, silver-haired twin in a swan-feathered white tutu. Mechanically, the 2×2 Lunar Zone stops resetting between spins, building a progressive multiplier across the whole bonus while hopping to a new position on every spin and every cascade. It also introduces the Night Bloom symbol (1.33 per 100 cells), a purple chrysanthemum marked with a question mark that adds between +2x and +100x (2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, or 100x) to the progressive zone multiplier when it lands inside the moving 2×2 square. Because that target covers only 4 of the 36 cells on the board, most chrysanthemums land outside the frame as closed buds that block cluster connections without adding anything to the counter.
Darkside Destiny (200x the bet, 96.33% RTP) is the only mode rated at high volatility, and it flips the visual theme a second time: the "Darkside" super-bonus opens into a blindingly bright cornflower-blue and white astral sanctuary traced with astrolabe rings and lunar phases, replacing the solid character model with a translucent, cloud-lined silhouette of the long-haired princess. On the grid, the roaming Lunar Zone expands from 2×2 to 3×3, more than doubling its footprint from four cells to nine, a full quarter of the 36-tile board. That wider net not only catches Night Bloom flowers and multi-tile clusters far more often, but also unlocks the Wild Booster birdcage symbol. Whenever a birdcage lands inside the 3×3 frame, it scatters 2 to 5 Wilds onto random non-scatter cells, welding high-symbol clusters across the 10-symbol paytable jump right as the progressive multiplier climbs into double digits.
FeatureSpins and Bonus Buy menu
Hacksaw splits its paid menu into three ongoing FeatureSpins modes and the two direct bonus buys:
| Product | Price | What it buys | RTP |
|---|---|---|---|
| Crystal BonusHunt FeatureSpins | 2x the bet per spin | Each spin is 3 times more likely to trigger a bonus | 96.25% |
| Midnight BonusHunt FeatureSpins | 5x the bet per spin | Each spin is 10 times more likely to trigger a bonus | 96.18% |
| Lunar FeatureSpins | 50x the bet per spin | A Full Moon expansion of the Lunar Zone on every spin | 96.38% |
| Brightside Blessing | 60x the bet | 10 free spins with a progressive 2×2 Lunar Zone | 96.35% |
| Darkside Destiny | 200x the bet | 10 free spins with a 3×3 zone and Wild Boosters | 96.33% |
The three FeatureSpins options charge their listed price on every single spin and stay switched on until the DISABLE button is pressed. Crystal BonusHunt is identical in cost, odds, and return to the standalone BonusHunt toggle sign perched to the left of the reels, while Midnight BonusHunt pushes the bonus trigger odds to 10x at the cost of the lowest RTP on the menu (96.18%). Both BonusHunt modes only raise the likelihood of landing scatters; neither guarantees a bonus trigger.
Lunar FeatureSpins guarantees a Full Moon inside the Lunar Zone on every spin, expanding the multiplier frame across all 36 cells from the very first drop. Because the Full Moon lock prevents FS scatters from landing at all, this mode can never trigger free spins, making it a pure single-spin cascade gamble running on the highest RTP setting on the menu (96.38%).
Where it sits in Hacksaw’s lineup
Eclipse Princess sits beside Hacksaw Gaming’s cluster slots Dusk Princess and Rainbow Princess. Both of those run on smaller 6×5 boards with 10,000x max wins, whereas Eclipse Princess widens the grid to 6×6 (36 cells) while cutting the max win in half to 5,000x.
Stacked against the studio’s broader cluster catalog, that 5,000x ceiling places it well below heavyweights like Le Outlaw (25,000x), Le Gift Grabber (15,000x), Dragon’s Pub (10,000x), and Le Panda Town (10,000x). Instead, it settles into the calmer tier shared by Supernova Shooting Stars and Marlin Masters Frozen Frenzy, and doubles the 2,500x cap of Le Bandit Monsters Unleashed, while its 96.30% base RTP matches studio staples Rocket Reels and Mighty Masks.
At 200x the bet, Darkside Destiny is the only place where Eclipse Princess puts all of its advertised mechanics on the grid at the same time. The cell-counting math inside the Lunar Zone is a genuinely clever twist on Hacksaw Gaming’s cluster formula, turning a four-tile overlap into a heavy multiplier boost and making the 50x Lunar FeatureSpins mode (at 96.38% RTP) a sharp, bonus-free alternative when the full 36-cell expansion is forced on every drop. Yet by keeping the Lunar Zone at just four cells out of 36 in both the base game and the 60x Brightside Blessing bonus, the slot leaves its Night Bloom flowers and sub-10-symbol clusters stranded outside the frame far too often, charging more than triple the standard buy price to widen the box to 3×3 on a capped 5,000x ceiling.
