Two optional features.

Solo only · nominal bet is the basis of returns
Feature	Cost	What changes
Ante	Bet + 25%	2× Ascension chance
Ante Plus	Bet + 50%	3× Ascension chance
Ante Max	Bet + 100%	5× Ascension chance
Bonus Buy	9× / 18× / 30× bet	Ascension / Pulse / Zenith

Opening a quote costs nothing. Ante starts off and needs an explicit choice; Bonus Buy needs a separate purchase confirmation. Neither guarantees a profit.

Ante Bet · exact cost, odds & exclusions

Ante Bet · optional enhanced feature chance

With ANTE BET on, a paid Solo spin costs the nominal bet plus 25%, 50% or 100%, depending on the selected Ante. The supplement is rounded up to 0.001 cr and the exact total is displayed before you play. The chance of 3 Aurora diamonds on the centre line — and therefore of Ascension — is multiplied by exactly 2, 3 or 5 respectively at the current Aurora level. Other centre-line outcomes become proportionally less frequent. Returns still use the nominal bet, and Resonance keeps the same conditional rules.

Ante Bet is off when the page opens. Select it to review the extra cost, feature chance and current theoretical return, then confirm your selected Ante. You can turn it off between rounds. It does not apply to Bonus Buy, Ascension free spins, Pass turns, gift turns or Arena. It never guarantees a bonus or a win. Room ranges refer to the nominal bet; the supplement is charged in addition. The current combined theoretical return is shown in the Ante panel and paytable; it differs from ordinary play.

Bonus Buy · price, returns & restrictions

Bonus Buy · three routes

In Solo, choose Ascension: 9× bet, 5 spins, Pulse: 18× bet, 6 spins or Zenith: 30× bet, 8 spins. Each card shows the exact price before confirmation. Opening, changing a selection or cancelling costs nothing. Confirmation deducts the price once; the bet and symbol finishes stay fixed through the feature.

The ladders are Ascension 1×, 1×, 2×, 2×, 3×; Pulse 1×, 2×, 2×, 3×, 4×, 6×; Zenith 1×, 2×, 2×, 3×, 4×, 5×, 6×, 7×. A multiplier applies to the complete line + Resonance return. There is no extra stake and no retrigger.

At a 2 cr nominal bet, the three prices are 18, 36 and 60 cr. All three have a 92% theoretical purchase return. A return can be zero or below the purchase price; a purchase does not guarantee a profit. Bonus Buy is unavailable during a spin, autoplay or another feature, or without enough credits. Promotional gifts are excluded from these theoretical returns. Fictional demo credits only; no real payment.

Build your private collection.

Open Atelier for museum objects. Open Menu → Rewards & invitations for private panoramas. They use separate balances.

Three distinct balances
Balance	Used for	Where
Demo cr	Solo bets / separate Arena wallet	Game controls
Cosmetic credits	Collectible objects	Atelier
Collection points	Private panoramas	Rewards

Objects

Inspect any of the 15 objects for free. The Curator Drop offers three each UTC day. Acquire an available object with cosmetic credits, then show or hide it in its world. Up to 15 collected objects can be displayed per world, at half the previous floor size.

Private panoramas

Preview the four new worlds, unlock one with points, then equip it. Unlocks are permanent for your collection identity. Restore the original scenery whenever you want.

Earning credits, ranks & the demo Pass

You start with 1,000 cosmetic credits. Claim the 50-credit daily gift in Atelier. Weekly quests award 50 for visiting all five worlds, 75 for finishing a duel and 75 for 10 active minutes. An Arena winner also receives cosmetic credits equal to the game share.

Relics cost 160 / 280 / 420 cosmetic credits and grant 35 / 60 / 90 collection XP by rarity. Six ranks use thresholds 0, 100, 240, 420, 650 and 900 XP. Appearance and rank do not alter game probabilities or returns.

The free demo Pass lasts until the end of the UTC month and grants two Star turns that month. Pass and gift turns do not trigger Ascension.

Points, invitations & saved progress

Rewards gives 40 welcome points and 20 for your first visit each UTC day. The four panoramas cost 100 / 140 / 180 / 220 points. An invited friend qualifies after returning on another UTC day at least 20 hours after their first visit. Milestones at 1 / 3 / 5 / 10 / 20 guests give three turns in Gold / Blue / Red / Abyss / Star respectively.

Atelier objects, cosmetic credits and finishes are saved in this browser when storage is available. Rewards keeps a server-side collection linked to this browser’s identity. Clearing browser storage loses that link; this is not an account shared across devices. Solo balance and unfinished Ascension sessions are not retained after reload. None of these balances has monetary value or can be cashed out.

Daily editions & room rewards

Connect on a UTC day to receive the next piece in your 30-piece treasury, without a bet. Missed days preserve your place. After completing the series, your 20 daily collection points continue. New pieces arrive with future series. Your pieces can be placed on the floor of their own world from Atelier.

Activity days accumulate separately for each world, with no reset for missing a day. Every 7 activity days adds an allowance of up to 5 same-world turns; every 28 adds up to 2 next-world turns, or 5 in Star. These are funded allowances, not guaranteed weekly payouts. 0.5% of paid Solo stakes funds the budget; each turn costs 92% of its nominal stake from that budget. Unfunded allowances wait. Existing credited turns remain yours with no expiry.

Free turns use the world’s minimum nominal bet: Gold 1 cr, Blue 2 cr, Red 10 cr, Abyss 25 cr, Star 100 cr. Gift, Pass, bonus and Arena turns do not validate a paid day. Bonus purchases alone do not validate it. Promotional gifts are additional and are excluded from the displayed per-spin and Bonus Buy theoretical returns.

The complete rules, within reach.

The tables show mathematical returns. Individual results vary. No outcome is owed after a losing streak.

Worlds & bet ranges

Five rooms · five bet ranges

All amounts are fictional demo credits per spin, not deposits. Gold: 1–2; Blue: 2–9.99; Red: 10–24.99; Abyss: 25–99.99; Star: 100–10,000 (demo cap). A 2 cr bet is accepted in both Gold and Blue. Bets outside a room's range show the suitable room; changing rooms requires a click and never spins automatically. Your balance carries between rooms; changing rooms does not add credits. New session resets the demo balance to 1,000.

Every room uses the same 92% theoretical base-game RTP and the same two-game rules. Paid Solo spins also qualify for Ascension; see the additional return below. Arena, Pass and gift turns do not trigger Ascension. Changing only the nominal bet does not improve the odds. The optional Ante Bet changes the distribution as explained above. The level-I artwork now starts at the previous level-IV richness, with five new visual finishes and increasing inner light. Artwork does not change the level rules or payouts.

Turbo, autoplay, history & session

Speed and autoplay

Turbo shortens the presentation only; the same result is drawn and settled. Autoplay plays a selected batch of 5, 10 or 25 demo spins at the current bet. Stop it at any time with the AUTO button or Escape; a spin already started still settles once. Autoplay stops when the page is hidden, you switch worlds or modes, your bet changes, or the balance is insufficient. Autoplay continues after ordinary wins by default. You may enable Stop after a net win before starting. A newly unlocked Ascension feature still pauses autoplay for explicit entry.

History replays are free and do not change balance or progression. Settings → New session resets the Solo demo balance to 1,000 cr. Saved collection and finish progress are separate.

Current odds & theoretical return

Full distribution & probabilities

Distribution and probabilities

The complete grid follows a weighted joint distribution, not nine independent equally likely draws. For each named centre triple at level L, probability is 7 / (1,350 × L). Two matching centre symbols have a combined probability of 46⅔%. Triple frequency is lower than in versions 6.x to fund the extra Resonance returns.

Conditional on three different centre symbols, probabilities for exactly 5 / 6 / 7 / 8 / 9 matching objects are 6% / 2% / 0.5% / 0% / 0%. With a centre pair: 5% / 2% / 0.5% / 0.125% / 0%. With a centre triple: 4.5% / 2% / 0.5% / 0.125% / 0.025%. The remaining probability gives no Resonance. The matching symbol is chosen uniformly among symbols capable of reaching that count; its outer-cell positions are shuffled uniformly.

Internal base-game theoretical return at every finish combination: centre line 68% + Resonance 24% = 92%. These values are mathematical expectations, not promised results or independent certification. Spins are independent conditional on the current finishes; no win is owed. The final-reel slowdown does not change the drawn result.

Choose 1 to 10,000 fictional credits within the selected room's range and the available balance, with at most two decimal places. Half-cent returns are kept exactly. Demo credits have no monetary value. This version is not connected to a real-money platform.
