Coin Lamp (3 Oaks Gaming (Booongo)) – Review & Demo Play

Coin Lamp Basic Information

Coin Lamp runs on a 4x3 grid with a single betway, and the bet range starts at €0.2 and goes to €30 per spin. You pick from three spin speeds, and autoplay keeps going without a set limit. This is a high volatility slot with a 2,000x max win, and the base game does not pay at all. Everything points towards the Bonus Game, so most sessions revolve around setting up the middle row while watching for that sticky coin to land in view.

Coin Lamp Features

The base game is all about triggering the Bonus Game, and the sticky bonus symbol lends a helping hand as it stays in place until the end of the next bonus game. The feature is a hold and win-style round where you can open up to three extra top rows, get random position multipliers, and even see random upgrades to stronger bonus tiers. Landing any type of bonus coin on all four middle positions is the doorway to the action.

Each of the three bonus tiers adds special symbols, with Collectors, Jackpots, and Mystery coins in the mix. The top-tier Power Bonus Game begins with all three top rows already opened and guarantees position multipliers. Filling the entire grid is the path to the 2,000x Grand Jackpot, which then cancels all other prizes. For non-UK markets there is a Bonus Buy where eligible players can enter the bonus, super bonus, or power bonus for 40x, 100x, or 200x stake.

Coin Lamp Bonus Game

The Bonus Game triggers when any bonus symbol lands on each of the four positions on the middle row, and you begin with three respins. All bonus symbols from the trigger spin follow you into the feature, and any new bonus symbols become sticky for the duration. At random times the Multiplier Feature adds x2 to x10 to two to five positions, and if a multiplier is already present the values stack. Multiplier positions apply to the held coin at the end.

The top three rows start locked. Landing eight bonus symbols opens row four, a further three opens row five, and another four opens the final row. The respin counter resets to three whenever a new coin lands, and the round stops after three dead spins. If you manage to fill all twenty four positions with bonus symbols, the game awards the 2,000x Grand Jackpot. As this is the win cap, any separate winnings are forfeited once it hits.

The Super Bonus Game and the Power Bonus Game can appear at random during a regular bonus. Super guarantees the multiplier feature at the start and makes it appear more often while it lasts. Power mirrors Super but starts with all three top rows opened from the outset, so the grid is fully open from spin one. In practice, those upgrades carry the most excitement as multipliers tend to climb and shape the final tally in a noticeable way.

Coin Lamp Symbols and Paytable

Regular Bonus Symbols land with values from 0.5x up to 4x stake. The Sticky Bonus coin, marked by a red circle, carries 5x to 9x and stays until the end of the next bonus game, and it helps to trigger the feature when it lands on the middle row. Mystery Symbols reveal any bonus symbol except the sticky coin, and Mystery Jackpot coins reveal a Mini, Minor, or Major worth 10x, 20x, or 50x. Collector Symbols absorb the values of all present bonus coins.

Theme & Graphics in Coin Lamp

The 4x3 gold-framed grid sits against a thunderstorm sky streaked with lightning that paints the clouds a purple hue. A glowing magic lamp perches on top and crackles as coins tumble into the treasure beneath. The audio leans into a mysterious Arabian soundtrack, and you will see energy sphere mystery symbols and gold coin bonus symbols popping into view across the reels. It is a bold look that fits the hold and win pace without clutter or needless distractions.

Pros and Cons of Coin Lamp

Sticky Bonus Symbols can help trigger the Bonus Game, and the feature comes with special symbols and multiplier positions that can add up in satisfying ways. You can open up to three extra rows during the bonus, and there is a random upgrade to Super or Power bonus games that often changes the tempo. Filling the grid awards the 2,000x Grand Jackpot, and multipliers can stack across positions, so pacing the spins and watching for progress feels engaging enough.

On the downside, you cannot win anything in the base game, and the slot leans a bit too similar to other coin slots on the market. There is no configurable volatility, and the bonus hit rate is not disclosed, which would be handy to know. The row opening requirement can feel frustrating during cold spells as the grid growth stalls. If you are fine with that style, the bonus can still deliver decent bursts when the multipliers co-operate.

Our Verdict on Coin Lamp

As a high volatility hold and win outing, Coin Lamp is built around its feature loop rather than base game thrills, and that focus comes through straight away. The sticky coin is a smart nudge towards the trigger, and the random upgrades keep the round from feeling static. I rate the multiplier positions highly as they stack neatly and give you a clear target. Without base wins, though, stretches can drag while you set up the middle row again.

I see enough polish in the visuals and the upgrades to give it a spin when I want that specific coin style. The 2,000x cap limits headroom, and the similarity to familiar coin formats is plain, yet the progress of opening rows and the promise of a Power start can carry sessions. If the studio leans further into its own twists next time, the series could land stronger. For now, Coin Lamp shines brightest during those upgraded bonuses.
