Visually, Grand Spinn has a 1920s Art Deco theme – with burgundy and gold dominating the colourings, it has a sophisticated feel to it. Symbols include blank symbols (yes, really), bars, cherries, plums, oranges, watermelons and treble 7s. The latter is the most rewarding with 3 on a payline giving you 20 times your stake.

You form winning combinations by getting matching symbols across all 3 reels. When you win, the Nudge feature is triggered. If the top symbol on the first reel is the same as the winning symbol, the first reel nudges down 1 position with the win awarded again.

Furthermore, the reel continues to nudge until the symbol above the winning one is different meaning you can win again and again if the symbol matches. Furthermore, the process is then repeated for reel 2 and then reel 3. Once the reels stop nudging, an up arrow symbol may appear at the top of a reel – the reel then moves to the bottom of the current stack of winning symbols. The reels then begin to nudge and pay from this position.

For example, if you got 3 triple 7s across the payline and there’s a triple 7 on the top position on reel 1, it will nudge down to give you the same win again – so 40 times your stake. This can happen on reels 2 and 3 to give you even more wins.

Look out for Multiplier Wild symbols on reels 1, 2 and 3 – these replace all symbols except the arrow symbol and Jackpot symbols. Known as the Multiplier Wild feature, you can get up to 3 Multiplier Wilds in play:

• 1 Multiplier Wild will subject your wins by a 2x multiplier
• 2 Multiplier Wilds will subject your wins by a 4x multiplier
• 3 Multiplier Wilds will subject your wins by an 8x multiplier

When all reels have stopped nudging, you might see Jackpot symbols at the top of the reels – this can trigger the Jackpots feature. If each reel has a Jackpot symbol above the winning stack, you will win the lowing paying Jackpot from the present Jackpot symbols. For example:

• If you were to see 3 Mega Jackpot symbols, you’ll win the Mega Jackpot
• If you saw 2 Mega Jackpot symbols & 1 Midi Jackpot symbol, you’ll win the Midi Jackpot
• If you got 1 Mega Jackpot symbol, 1 Midi Jackpot symbol & 1 Mini Jackpot symbol, the Mini Jackpot is won

Now, the size of the jackpot depends on which version of Grand Spinn you are playing. There’s also a Grand Spinn Superpot slot which is the same but has progressive jackpot versions – here’s what you could win with both versions:

When it comes to the Grand Spinn Superpot version, the progressive jackpot will be a minimum of £500 – however, the progressive jackpot is local to each online casino meaning the same amount won’t be offering across all online casinos. For example, the progressive jackpot will differ from NetBet Casino and LeoVegas Casino.

Jackpots aside, the win potential from the Nudge feature and Multiplier Wild feature is exactly the same in Grand Spinn and Grand Spinn Superpot – you can pocket a whopping 7,040 times your stake if you get 3 Multiplier Wilds (8x multiplier) and the maximum number of nudges.

The potential of a progressive jackpot is great but the chances of winning it is pretty slim – I would opt for the Grand Spinn version as you can still win big (up to 7,040 times your stake) as well as winning 10,000 times your stake from the Mega Jackpot.

Overall, Grand Spinn, and Grand Spinn Superpot, are decent slots – they look good and have the potential for big wins. It’s definite one for fans of classic fruit machines with a couple of twists. If you want bonus features that are more modern, NetEnt’s Dead or Alive II cannot be beaten as it offers 3 free spins features with 1 of them potentially paying out 111,111.11 times your total stake!
