The energy diamonds are the game's centrepiece, glowing symbols that accumulate on the reels and trigger the Hold and Win bonus round when enough land in the right configuration.

| Wild Star | $50.00 | -- | -- | -- |

Wild Symbol
The Wild Star lands on the reels and substitutes for any regular paying symbol. Its 5-of-a-kind payout of $50.00 at a $1 bet is the highest available outside the Hold and Win feature, making Wild combinations the most impactful base-game events.
Hold and Win Feature
The Hold and Win bonus is the game's primary feature. When a qualifying number of energy diamond symbols land on the reels, the feature triggers. During the bonus, all energy diamonds that contributed to the trigger are held in place while the remaining positions respin.
Each respin that lands new energy diamonds locks them in position and resets the spin count back to three. The feature ends when no new diamonds land or the grid fills. Diamonds carry individual values, and the total of all locked diamonds is paid at feature end.
The Increase, Collect, and Expand special diamond types visible during the feature each modify the outcome: Increase raises individual diamond values, Collect gathers values from adjacent positions, and Expand extends diamond placement to additional grid positions.
Double Chance Bonus Buy
A Double Chance option is available as a bonus buy. At 1.5x the base bet per spin, it doubles the probability of triggering the Hold and Win feature on that spin. At a $1 bet, activating Double Chance costs $1.50 per spin. It does not affect individual payouts once the feature triggers, only the likelihood of entry.
Mobile Experience
3 Energy Diamonds: Hold and Win runs in-browser on iOS and Android without a dedicated app. The 5x3 grid scales cleanly in portrait mode, bet controls are accessible from the main spin view, and the Double Chance toggle is available without switching orientation. The Hold and Win animations render clearly on mid-range devices.

Top Tips for Playing 3 Energy Diamonds: Hold and Win
Use Double Chance as a session tool, not a constant
The Double Chance option at 1.5x base bet increases feature entry probability but raises effective cost per spin by 50%. At low volatility, the base game already triggers the Hold and Win feature more frequently than a high-variance title would. Using Double Chance on every spin is defensible only if your session budget is built around that cost. Selective activation is more efficient for session longevity.
Scale your bet to your session goal, not the ceiling
The 5,200x max win is achievable in a well-constructed Hold and Win round, but low volatility means the feature returns a range of outcomes across sessions, most of which sit well below the ceiling. Setting a bet level where 100 or more spins fit comfortably in your budget is the most rational approach for this game's profile.
