Coin Spark RTP and Wagering

Coin Spark - RTP and Wagering

Coin Spark is played on a simple set of three reels with three rows and five fixed paylines. The aim is to line up three matching symbols on any of those paylines, as in a traditional slot game.

The bets range from £0.05 to £5.00 for adults aged 25 and over in the UK. But the maximum bet for players in other countries can reach up to £50.

This slot game has medium volatility and a theoretical RTP of 96.28%, which is higher than the 96% industry average. The maximum win available is 5,000x your bet, and unlocking the Bonus Game may help you land that top prize. I’ll explain how the Bonus Game works later in this Coin Spark review.

Best Casinos to Play Coin Spark

Coin Spark is at a wide range of UK online casinos. To help you choose the right place to play it, here are the best slot sites:

Coin Spark Symbols and Audio & Video Design

Coin Spark is modelled on traditional slot machines, and its classic look should seem familiar if you’ve played other games using the same theme.

While it might not be original, Coin Spark’s presentation is still easy on the eye, with lots of colour and retro charm. It has a vivid blue background and chunky symbols that seasoned players will have seen in many similar slots. Lemons, grapes, apples, and more classics can land across the reels.

The most valuable symbol is the triple 7, which pays 50x your bet for three. The lowest-paying symbol is the cherries, which is worth 2.5x your bet. As you can see, the standard symbols only offer very small payouts.

  • Cherries: 3 - 1x bet
  • Lemon, Orange, Apple: 3 - 4x bet
  • Grapes, Watermelon: 3 - 16x bet
  • BAR: 3 - 20x bet
  • Bell: 3 - 30x bet

Coin Spark Mobile Features

Coin Spark has been designed for desktop and mobile. Using a mobile browser, you can play it on a smartphone or tablet at various slot sites. The graphics are still bright and colourful on a mobile, and the controls remain easy to handle. With its responsive design, Coin Spark supports portrait and landscape modes too.

Coin Spark Bonus Features

While it’s based on simple slot machines, Coin Spark still includes bonus features for added depth and extra winning chances.

Wild Symbol

The triple 7 symbol is the Wild. It will substitute for all other paying symbols except the Bonus and Bonus Collect symbols.

Bonus Game

Bonus symbols can hit on reels 1 and 3, while Bonus Collect symbols only land on reel 2. If you land these symbols at the same time, you’ll trigger the Bonus Game. All the triggering symbols stay locked into place.

At the start of the Bonus Game, you have three spins. Only Bonus and Bonus Collect symbols appear. But empty positions can randomly award prizes of between 1x and 15x your bet, as well as jackpots.

Bonus Collect symbols collect Bonus symbols. The value of any collected Bonus symbol is added to the Bonus Collect symbol’s total. Each time a Bonus or Bonus Collect symbol lands, the number of remaining spins resets to three.

If you finish the three spins without landing any Bonus symbols or your total collected winnings are worth 5,000x your bet, the round ends.

Bonus Game Jackpots

Jackpot symbols can appear randomly in the Bonus Game and award the prize shown. Four jackpots are available:

  • Mini – 25x bet
  • Minor – 50x bet
  • Major – 150x bet
  • Grand – 1,000x bet

Bonus Blast Feature

The Bonus Blast feature can trigger randomly in the base game. It adds extra bonus and Bonus Collect symbols to help you trigger the Bonus Game.

Instant Win Feature

If a Bonus Collect symbol appears with one or more Bonus symbols (even jackpot ones) without triggering the Bonus Game, the Instant Win feature activates. The Bonus Collect symbol collects the other symbol values and adds them to the spin’s total win.

Coin Spark Final Thoughts

Coin Spark is a simple slot on the surface, but the bonus features make for a deeper gaming experience than you might expect. It’s not original or particularly fresh, but the game is entertaining all the same. 

You also have the chance to land some decent wins during the Bonus Game, thanks to the familiar collection mechanic. Coin Spark has an above-average RTP and medium volatility too.

While the top prize of 5,000x your bet should make the game appealing to casual players, the standard symbol values are tiny. As a result, you may only grab some of the better prizes in the Bonus Game.

Still, if you’re on the lookout for a classic-themed slot that includes bonuses and is easy to learn, Coin Spark may be right for you.
