How Diamond Explosion 7s pays
The game rules inside RubyPlay's free demo describe 'a 5-reel, 3-row video slot featuring Free Games, Jackpot Pick Deluxe, and Link It Up Explosion', and 'The game is played with 50 lines.' The paytable scales with the total bet, so every pay below is a fixed share of the spin.
Line wins pay 'in order from the leftmost to the rightmost reel', 'Only the highest win per bet line or way is paid', and wins on different lines are added. Three symbols follow rules of their own. The game's logo is the wild and, in the base game, 'Substitutes for all paytable symbols except PRIZE and SCATTER'. The horseshoe is the scatter and 'Pays anywhere on the reels'. The diamond is the PRIZE symbol, which feeds Link It Up Explosion rather than a line.
Only the sevens pay for two of a kind. On a R10 spin three of a kind returns R1 for every symbol but the seven, by our arithmetic from the table below. RubyPlay's game page gives a hit frequency of 48.24%: about half of all spins return something, while one three-of-a-kind line returns a tenth of the spin.
What a line pays on a R10 spin
The PAYTABLE screen of RubyPlay's free demo shows these amounts at a total bet of 1.00 in euro; we multiplied them by ten for a R10 spin, as the rules scale the table with the bet, and named the fruit from the pictures. The horseshoe row is a scatter pay on the whole bet.
| Symbol | Five | Four | Three | Two |
|---|---|---|---|---|
| Horseshoe (scatter) | R200 | R50 | free games only | - |
| Seven | R50 | R10 | R2 | R0.40 |
| BAR | R40 | R6 | R1 | - |
| Bell | R30 | R5 | R1 | - |
| Clover | R30 | R5 | R1 | - |
| Watermelon | R20 | R4 | R1 | - |
| Lemon | R10 | R2 | R1 | - |
| Grapes | R10 | R2 | R1 | - |
| Plum | R10 | R2 | R1 | - |
| Cherries | R10 | R2 | R1 | - |
Link It Up Explosion: diamonds that join into shapes
'During base game 6 or more PRIZE symbols trigger Link It Up Explosion.' The feature gives '5 Explosion Free Games'. The diamonds that started it lock, and 'remaining reel positions become individual reels'. Any diamond that lands after an Explosion Free Game holds its position until the end.
At the end of each Explosion Free Game, adjacent diamonds 'combine to form the biggest possible shape(s)', horizontal or vertical, and 'Each PRIZE symbol can only be part of one shape.' The feature ends when no Explosion Free Games remain or every position is held, and the values shown on all the diamonds are paid.
What each diamond shape can pay
The shapes and prizes as the PAYTABLE screen of RubyPlay's demo lists them, with the rand amounts on a R10 spin by our arithmetic. The screen does not say how a value inside a range is chosen.
| Shape | Prize on the rules screen | On a R10 spin |
|---|---|---|
| 1x1 | 1x total bet | R10 |
| 1x2 | 3x total bet | R30 |
| 1x3 | 5x total bet | R50 |
| 2x2 | 6x to 20x, Mini or Minor | R60 to R200 |
| 3x2 or 2x3 | 10x to 35x, Mini or Minor | R100 to R350 |
| 4x2 | 15x to 40x, Mini or Minor | R150 to R400 |
| 3x3 | 20x to 45x, Minor or Major | R200 to R450 |
| 5x2 | 30x to 60x, Minor or Major | R300 to R600 |
| 4x3 | 40x to 80x, Minor or Major | R400 to R800 |
| 5x3 | 100x to 225x, Major or Grand | R1,000 to R2,250 |
Jackpot Pick Deluxe: four fixed prizes and a multiplier
'During base game or free games, WILD symbol randomly triggers Jackpot Pick.' Twelve coins appear and you keep picking 'until 3 jackpot levels match'. The prizes are fixed shares of the bet: 'Mini = 10x total bet, Minor = 15x total bet, Major = 50x total bet, or Grand = 800x total bet.' Picks 'may also reveal a multiplier: 2x, 3x, 5x, or 10x', and if the matched three contain one, the prize is multiplied by it. Line wins are paid before the pick.
These jackpots do not grow with play. On a R10 spin the Grand is R8,000, and a Grand with the 10x multiplier would be R80,000, or 8,000 times the bet by our arithmetic - the same figure RubyPlay's game page gives as the max win. The page does not say how that figure is reached, and the rules state no win cap.
Free games: one reel of wild diamonds every spin
Three or more horseshoes start the free games. The PAYTABLE screen lists three scatters as 8 free games, four as '8 free games and 5x total bet' and five as '8 free games and 20x total bet', the same amounts as the scatter pays in the table above.
'During each Free Game, a random reel is chosen where each symbol is both a Wild and a Prize.' In the free games the wild also stands in for the diamond ('substitutes for all paytable symbols except SCATTER'), and diamonds together with the combined wild-and-diamond symbols count towards the six that start Link It Up Explosion. Three more horseshoes during the free games add another 8.
