Sports are a theme online casino developers seem to like. Many of them have been adapted into slot machines like football, with Soccer Safari and World Cup; golf, with Hole in One; or even horse-racing with such examples as Champion of the Track and Sure Win. Even some rarer sports like bowling have been adapted, with Strike\'m\'up.

The Heavyweight Gold slot machine from Rival we are discussing here deals with English boxing. Let\'s see if this slot machine deserves to be called a heavyweight.

Quick overview

Heavyweight Gold offers 5 reels and 20 payment lines. With an average variance, it also offers a pay-out rate of 96%. The game offers a Wild and a Scatter which allows you to win free spins. Like the other interactive slot machines known as i-slots, developed by Rival, it follows a storyline all through your game session. After time travel in A Switch in Time and a spying mission in Spy Game, you will now follow the exciting career of a boxer through 3 bonus games which follow the same principle.

Bets

You can bet between 1 and 10 coins per line and you can choose between the following values: 0,01, 0,05, 0,10, 0,25 €/$/£. The range of bets is acceptable with a minimum bet of 0,01 €/$/£ and a maximum bet of 50 €/$/£.

Wild

The boxing gloves are Wild. They only appear on the first three reels and can replace the other items, except for the Scatter and the symbols which trigger the bonus game. Once you get it on screen, it expands throughout its reel. It is an expandable Wild.

Scatter and free spins

The lovely young lady is a Scatter. If you get it 3, 4 or 5 times anywhere on the reels, you win respectively 10, 20 or 100 free spins during which the amount you win is multiplied by 3. These free spins are also re-triggerable.

Bonus game

When you get 3, 4 or 5 symbols depicting the same opponent (a skinny man, a Mister T look-alike or a long-haired brute), you trigger a bonus game during which you fight this adversary.

During the match, you need to choose whether to strike or to par. You will win money depending on your choices. This feature is like a less-developed version of the Crusade of Fortune bonus game from Netent.

Compared with the other Rival i-slots, Heavyweight Gold is slightly less innovative, as its three bonus games are basically the same and that the story-line is more discreet. However, this game remains a masterpiece, far superior to your average slot machine.
