Diamond Crucible

Pressure Release

A materials scientist grows luminous crystals inside a high-pressure laboratory deep beneath the mountains.

Awarded specimens clear and a second recorded layer settles into the field.

Reels and awards

Six reels, four rows. Matching symbols pay from the leftmost reel across at least three consecutive reels. All matching positions on those reels form winning ways. Wild substitutes for ordinary symbols. Values below are multiples of the selected play level per winning line or way.

All eight ordinary symbols use this table. Recorded feature multipliers apply to the displayed winning field. The entire round, including follow-up frames and resource collections, is capped at 250× the play level. Credits are whole fictional units.

Signature feature

Awarded specimens clear and a second recorded layer settles into the field. The second recorded layer is evaluated separately and its award is included in the round total.

Evolving Wilds

Each completed signature feature collects 1–3 resources according to the current Wild form. Every 12 resources unlock the next of six forms for this game and play level: Single, Celestial 2×, Expanding, Held, Travelling and Mega. Each form changes the recorded feature field. The new form starts on the next round. Progress is saved separately for every game and play level.

A high-award feature may include Hold & Spin. Locked resource values are shown on the board, new resources reset the counter and the final collection is included once in the server's round total.

Controls and interrupted rounds

Choose a play level and press Spin, or Space when focus is outside a control. Quick spin shortens reel timing. Autoplay is limited to the chosen number of rounds and can be stopped. Sound is off until you enable it. Replay presents a recorded round without using credits. An interrupted request can be retried with its original identifier.

Just for entertainment

Play Credits have no monetary value. No purchases, transfers, redemption, cash or prizes of value. Preview sequences are illustrative and do not represent the frequency of any result. A social game result does not predict real-money gambling outcomes.
