Lucky 8 Merge Up Slot Review
This number-based slot set on a 6x6 grid comes complete with a x5,000 top win, a cluster pays mechanic, cascading wins, free spins and win multipliers worth between x2 and x128. Here’s what else you can expect from this BGaming slot…
Will Your Lucky Number Land?
Number-based slots aren’t as prevalent as you might initially assume, so if you’re keen to try something a bit different, you might find what you’re looking for here.
Design
The plain blue background isn’t particularly inspiring, but this does allow the multicoloured number symbols to hold all the attention. The game does have a very youthful feel about it largely due to the colour choices that have been made, which will likely be quite divisive amongst online slots players.
Soundtrack
The main soundtrack is fairly generic but less peppy and upbeat than in similar online slots, which will certainly appeal to many. The additional sound effects when the reels spin and clusters land work well with the main track, which means gameplay never feels overly stimulating. But don’t forget sounds can be easily muted if that’s what you prefer.

How to Win at the Lucky 8 Merge Up Slot
Lucky 8 Merge Up is played on a 6x6 grid with a cluster pays mechanic. Players can win by landing clusters of at least four identical symbols. Larger payouts can be won by landing clusters of more than 12 identical winning symbols.
Top Winning Symbols
The paytable comprises different-coloured number symbols ranging from 0 to 7.
On a 0.20 stake, landing four mint green 0 symbols in a cluster will pay out a 0.02 win. Landing 12+ mint green 0 symbols in a cluster will award a 1.00 win. The pink 7 symbol is the highest-value standard paytable symbol, with a cluster of four awarding a 0.20 win and a 12+ cluster unlocking a 10.00 win.
Bet Limits
The minimum stake is 0.20.
Lucky 8 Merge Up Bonus Features
Many BGaming slots contain a selection of non-traditional bonuses, so let’s explore the additional features that may be triggered during the Lucky 8 Merge Up base game.
Merge Up
When four or more of the same paytable symbols form a cluster and the win has been awarded, some of those symbols will be removed from the reels and others will form into a new, higher-value symbol. So symbols from a cluster win featuring the yellow 4 will transform into an orange 5.
On every spin, merges are displayed on the left-hand side of the reels, so you can keep track of your gameplay easily.
Cascading Wins
As winning symbols are removed from the reels, this triggers the cascading wins function. So spaces on the reels are filled with new symbols falling from the top of the screen, which has the potential to trigger additional winning combos without needing to hit the spin button again.
Free Spins Bonus Round
The 8 scatter symbol can trigger the free spins bonus. The number of scatters that land determines the number of free games that are awarded.
- 4x scatter = 15 free spins
- 5x scatter = 18 free spins
- 6+x scatter = 20 free spins
The cells where the winning scatter symbol cluster was formed remain highlighted throughout the duration of the bonus round. If a marked cell is involved in a winning cluster, that win will receive a x2 win multiplier.
The multiplier of a marked cell increases with every win it participates in. So if the same cell is then involved in another win, the win multiplier value will be larger than x2. The win multiplier values range from x2 to x128.
Lucky 8 Merge Up Review Summary
Number-themed slots aren’t as prevalent as you might initially think, so Lucky 8 Merge Up is offering something a bit different to the norm. The x5,000 top win is a solid prize, and the Merge Up bonus feature offers extra chances to land higher-value cluster wins.
