RTP configurations

This game does not run at one fixed RTP. It ships 2 figures, and which one applies depends on the condition in each row — buying the bonus, an ante bet or a game setting. All of them were read off the game’s own rules screen.

Bonus modes

4 modes
Base Game Modifier base
Base Game

7x7 grid (49 cells), always fully filled, rectangular (not variable). Cluster pays only: 5+ same symbols connected orthogonally (up/down/left/right; diagonal-only contact does not count, per the paytable's green-check/red-X diagram) form a cluster, which pays and empties, refilling from above (cascade/tumble) repeated within one spin until no further wins form. No paylines or ways. Paytable tier '15' means '15 or more' connected symbols.

Other buy_bonus
Buy Bonus (Free Spins purchase)

Single purchase option (no tiers): costs 100x the current total bet, recalculated automatically whenever the bet changes; the purchase triggers the Free Spins round on the very next spin.

Free Spins free_spins
Free Spins

Triggered by 3+ Scatter (mine-shaft gate) symbols anywhere on the grid: 3->10, 4->12, 5->15, 6->20, 7->30 spins; retriggering during the round uses the same award table. Background switches to a more intense lava-lit cave look. Unlike the base game, Multiplier Spot marks and their multipliers are kept on the board for the whole round instead of resetting every spin.

Other multiplier_spot
Multiplier Spot

Persistent modifier active in both the base game and Free Spins. A winning cluster marks the cells it occupied. If a later winning cluster reuses a marked cell, that cell carries a multiplier starting at x2, growing with each further win on the same cell, capped at x128. When several marked cells belong to one winning cluster, their multipliers are SUMMED ('summarized' per the rules text), not multiplied together. Marks/multipliers reset at the start of every ordinary base-game spin but persist for the entire Free Spins round. UNRESOLVED (documented, not guessed): the rules phrase 'increasing by additional x2 with every new winning at this cell' is ambiguous between additive growth (2,4,6,8...) and doubling (2,4,8,16,32,64,128); only a single x2 step was observed live, so which progression is used could not be established.

Accessibility

profile for all groups
Color Blind
  • Primary risk: all 7 paying symbols are crystals/a nugget distinguished mostly by hue. Usable non-colour cue: high-value symbols are multi-shard CLUSTERS (or the uniquely shaped gold nugget blob), low-value symbols are always a SINGLE solitary shard -- shard count/shape signals value tier independent of colour.
  • Known weak point: the low-value 'small red-orange single crystal' and the high-value 'red-orange crystal cluster' share the same red-orange hue family; they can only be reliably told apart by counting shards (one shard = low value, a cluster of several = high value), not by colour.
  • The CLUSTER PAYS validity diagram in the paytable pairs a green checkmark (valid orthogonal adjacency) with a red X (invalid diagonal-only adjacency) -- shape-differentiated, not colour-only. Settings/Autoplay checkbox state is shown by presence/absence of a white checkmark glyph, not colour alone.
Screen Reader
  • Bottom-bar control layout is stable across all captured screens: info/settings icons far-left, balance centre-left, bet stepper centre, autoplay and spin buttons right. Paytable and Rules are each a single continuously-scrolling document (not paged with next/prev buttons), opened via the 'i' information button and closed with a top-right 'X'.
Motor Accessibility
  • Bet adjustment uses small up/down triangle steppers rather than a single +/- pair. Autoplay preset-count buttons (10/25/50/100/250/500/750/1000/unlimited) reduce the number of manual spin clicks needed. Spacebar can be enabled in Settings as an alternate spin trigger.
Hearing Accessibility
  • No information is conveyed by audio alone; Music and Sound FX are separately toggleable in Settings, and all game-state information (win amounts, free-spins counter, multiplier values, bonus price) is presented as on-screen text/numbers.

Data provenance

what we captured and what we didn't
Captured: preview/splash, base game (7x7 grid), paytable (12 pages: scatter rule, 4 high-value + 3 low-value symbol payouts, Multiplier Spot illustrated rule + diagram, cluster-pays orthogonal-adjacency diagram), rules (12 pages), settings, autoplay, bet floor (0.20 FUN) and ceiling (50.00 FUN), Buy Bonus dialog, Free Spins trigger + gameplay + Multiplier Spot in play + total-win screen, one base-game win screen.
Volatility rating is not stated anywhere across the 12 rules pages or 12 paytable pages (no flame icon, no numeric/text label) -- treated as not disclosed in this build, not guessed.
Multiplier Spot growth step is ambiguous in the rules text between additive growth (+2 per win: 2,4,6,8...) and doubling (2,4,8,...128); only a single x2 step was observed live, so the exact progression to the stated x128 cap is unresolved.
Quick Spin availability in this demo build was not further tested: the checkbox is present but unchecked in Settings, and the rules text notes the feature may be unavailable depending on license requirements.
payline_direction has no applicable value for this game: it is a cluster-pays game with no paylines/ways/direction concept (wins form from orthogonally adjacent symbols anywhere on the grid), so this field is intentionally left unset in this content pass rather than assigned a value.

What it looks like

How do the free spins in Crystal Clusters work? Keep it simple.

Triggered by 3+ Scatter (mine-shaft gate) symbols anywhere on the grid: 3->10, 4->12, 5->15, 6->20, 7->30 spins; retriggering during the round uses the same award table. Background switches to a more intense lava-lit cave look. Unlike the base game, Multiplier Spot marks and their multipliers are kept on the board for the whole round instead of resetting every spin.

So 'how many crystal points are grouped together' is a usable non-colour signal for value tier.

Marks and multipliers are cleared at the start of every ordinary base-game spin, but are kept for the whole Free Spins round. NOTE ON THE GROWTH STEP: the printed wording 'increasing by additional x2 with every new winning at this cell' is ambiguous between adding 2 each time (2, 4, 6, 8 ...) and doubling (2, 4, 8, 16, 32, 64, 128). Doubling is the more plausible reading because it makes the stated x128 cap the natural seventh step, whereas additive growth would need 64 wins on a single cell to reach it.

    "free_spins_total_win.png prints 'TOTAL WIN 11.50 FUN' with a caption '6 x BET' directly below it, at a Total bet of 2.00 FUN. Arithmetically, 11.50 / 2.00 = 5.75, not 6. The 11.50 FUN sum itself is independently corroborated by the balance change across the round (797.50 FUN before the Free Spins cycle began, rising to 809.00 FUN after -- a difference of exactly 11.50 FUN). Conclusion: the printed 'N x BET' caption on this summary screen is a ROUNDED display value, not the exact multiplier -- exact multipliers throughout this documentation were computed by dividing FUN amounts by the bet, never copied from an 'x BET' caption.",
    "A separate ordinary base-game win was cross-checked the same way: win_screen.png shows Total win 1.50 FUN at Total bet 2.00 FUN (balance 998.00 -> 996.00 during the win animation), which matches the teal crystal cluster's own printed paytable tier '5: 1.50 FUN' exactly -- confirming that ordinary (non-Multiplier-Spot) wins are plain multiples of the total bet with no rounding issue."

    "screen_reader": "Bottom-bar control positions are stable across all captured screens: info/settings icons far-left, balance label center-left, bet stepper center, autoplay and spin buttons right. The paytable and rules panels are each a single continuously-scrolling document (not paged with next/prev buttons) reached via the 'i' information button and closed with a top-right 'X'.",
    "motor": "Bet adjustment uses small up/down triangle steppers rather than a single +/- pair; Autoplay preset-count buttons reduce the number of manual spin clicks needed; Spacebar can be enabled as an alternate spin trigger (toggle in Settings).",
    "color_blind": "Primary risk is symbol identification, since all 7 paying symbols are crystals/nugget differentiated mostly by hue. Mitigations present in the game: high-value symbols are multi-shard CLUSTERS (or the uniquely-shaped gold nugget) versus low-value symbols which are always a SINGLE shard -- a shape/count cue independent of colour. Weak point: the low-value 'small red-orange single crystal' and the high-value 'red-orange crystal cluster' share the same hue family and can only be told apart by counting shards (documented above). The CLUSTER PAYS validity diagram in the paytable uses a checkmark/cross shape pairing, not colour alone. Checkbox and toggle states throughout Settings/Autoplay are shown via a checkmark glyph or switch position, not colour alone.",

    "Volatility rating: not stated anywhere across the 12 rules pages or 12 paytable pages captured; no flame-style icon or numeric/text volatility label was found. Treated as 'not disclosed in this build' rather than guessed.",
    "The exact intermediate multiplier progression of the Multiplier Spot beyond 'starts at x2, +x2 per additional win, capped at x128' is stated only as an additive step rule in the rules text; no explicit full list of intermediate steps (x2, x4, x6...) was printed anywhere, so the step sequence is inferred directly from the quoted rule text, not observed as an enumerated list.",
    "Whether Quick Spin is actually available in this demo build: the Settings panel shows the 'Quick spin' checkbox present but unchecked, and the rules text notes 'Depending on license requirements, this feature may not be available' -- availability in this specific build was not further tested.",
    "Multiplier Spot growth step: rules wording admits both additive (+2) and doubling (x2) readings; the x128 cap favours doubling, but this was not observed live and is not stated unambiguously anywhere in the 12 rules or 12 paytable pages."
