Firstly, I’m not complaining or suggesting about changing the multiplier on the return, I am suggesting an addition to it.
I have played and spent almost 50k in total on the slots and I’ve on many occasion had 2 ingots and 1 block of the same type or 2 blocks and an ingot, and been disappointed that there is no return on that. Obviously, if you match 3 coal, or iron, or any of the ingots you get a return for having a 3 pair of ingots. As with the blocks following the same pattern of getting a return with a 3 pair.
My suggestion is an addition to the current list of Returnable options. I feel that if you match 3 of a kind, that kind being: either 2 blocks and an ingot of the same type, and 2 ingots and a block of the same type. (Ex: 2 emeralds and an emerald block or 2 emerald blocks and an emerald.)
For example, say you are playing the Tier 1 slots and you get the following as a roll: Emerald, Emerald Block, Emerald. If the emerald currently has a return value of ~3.3x (10x return for 3 = ~3.3x per emerald) and the Emerald Block has a return value of ~33.3x (100x return for 3 = ~33.3x per block), then the total return value for a roll of 2 emeralds and an emerald block should have a return of ~40x. [((~3.3x * 2) + ~33.3x) = ~40x.] That being 100 gold on the Tier 1 slots, yielding 4,000 as a return with a roll of 2 Emeralds and an Emerald Block. Tier 2 yielding $40,000, and Tier 3 yielding $400,000.
Another example, but this time with gold. If you have a roll of 1 Gold Ingot and 2 Gold Blocks then you would receive a total multiplier of ~17.4x. A gold ingot currently has a return of ~.83x (2.5 return for 3 = ~.83x per gold ingot), and a gold block has a current return of ~8.3x (25x return for 3 = ~8.3x per block). So if you roll a gold ingot (~.83x) and 2 gold blocks (~8.3x *2) then you get a return value of ~17.4x. [((~.83 *2) + ~8.3x) = ~17.4x.] If you are playing on the Tier 1 slots your profits would yield $1,743. Tier 2, yielding $17,430, and Tier 3 returning $174,300.
