Epic Clover 100 Booster Slot by Fazi

The toggle on the left labelled Wild Booster is the lever that defines this game. Flip it on and your next spin is guaranteed a Clover Expanding Wild, with the toggle staying live until you switch it back off. The catch is the price: each boosted spin costs seven times your normal stake, while your line payouts still settle against the unboosted bet. So you are paying a premium purely to bend the odds, not to inflate the wins themselves.

What you are paying for is the green four-leaf clover, which only ever lands on reels two, three and four. When it shows, it stretches to fill the whole reel and turns every cell on it wild, standing in for everything except the two scatters. On a board running 100 fixed lines, a single fully wild middle reel feeds into a huge slice of them at once, so one clover often completes a stack of lines in the same drop. That is the entire win engine here, and with the Booster off it just has to arrive on its own.

The two scatters work differently from each other and neither one starts a free-spins round. The gold Star is the high payer and counts from any position on the screen, returning 100x your stake for five. The Red 7 scatter only registers on reels one, three and five, paying 20x for three. Both simply add to whatever your lines return. The red 7 also doubles as the top regular symbol and pays from just two of a kind, which softens the dry spells on a board otherwise packed with glossy bells, watermelons, blue grapes, oranges, cherries, lemons and plums, all sitting on a lush green field flecked with shamrock leaves and big golden 100 markers down each side.

Underneath sit three mystery progressives, Gold, Diamond and Platinum, that can drop at random on any base spin with no combination to chase, your odds scaling with how much you stake. Any win can be sent to a red-or-black gamble that doubles up to a 50,000 ceiling. It plays like a familiar Irish-luck fruit machine, but the buy-in toggle gives it a decision the cheaper clover slots in this family don't ask of you.
