Top O The Bonus Slot Game Review

Inspired Gaming have delivered an Irish themed slot game for their fans, as a successor to their original Big Bonus game.

Background, Visuals

The game starts on a background of a rainbow, thus adding to the Irish luck theme of this slot game. The reels are bright green to reinforce the Irish background, while the various symbols and icons are also similarly themed, as we will see further. Overall, the theme and visuals are quite retro, and this can be quite a decent experience for new slot fans who have not had a chance to play older slot games.


The game has six reels and four rows with 50 paylines. Players can bet from $/€/£0.20 up to $/€/£20 per spin. Wins are generated by landing at least three matching symbols on a payline, while more experienced players can take advantage of the autoplay option to speed things up.

If your game credit dips below the current stake, you’ll be given the option of a Spin Chance. This is on the proviso that the balance is above zero. A Spin Chance takes your remaining credit and allows you to win a full bet at the current stake. If you want to accept the offer, click on Play, and the pointer will begin to move around the meter. If it lands on green, you are awarded a free turn, but if it lands on red, you forfeit your remaining credit. The size of the red and green sections is calculated based on how much credit you have compared to the size of your stake. There’s no obligation to play Spin Chance; if you don’t want to accept, just click on No Thanks and proceed with topping up your balance or reducing your stake.


The game symbols are all Irish luck-themed, with even the low-value card royals from 10 to A showing up as bright coloured letters that add to the visual theme. The higher-value themed symbols include pots of gold, silver and bronze coins, along with a golden four-leaf clover and a wishing well. The green leprechaun hat is the game’s Wild symbol and can substitute for any of the high or low paying icons to make more matches. It is also the most valuable symbol, paying out 250x if you manage to land it across all six reels on a single payline. The four-leaf clover is the best of these from the regular symbols, giving you a 20x prize for six across a payline. The leprechaun itself is the game’s Scatter and will help trigger the Free Spins round.


Landing at least three of the Scatters on the reels will trigger the Free Spins round. Here, you will first get a ‘Pick Me’ round, with each of the Scatters on the reels turning into one of the options. Each of these picks now has a multiplier hidden behind it, ranging from 20x to 100x, and the multiplier that you pick will determine the length of the round. Once chosen, the free spins round begins, ending when you land a win that is the same or higher than the Pick Me multiplier that you chose at the start of the round. Thus, a prize is guaranteed in this round, which makes it different to the free spins rounds seen in most games.

Wilds that land during this round will stay locked on the reels.
