Star Clusters Megapays Slot by Big Time Gaming

Four progressive jackpots hang down the left edge, Mini, Midi, Major and the Mega, with the Mega starting at 300,000 euros and climbing with no ceiling as bets across the network keep feeding it. That ladder is what sets this apart from the original Star Clusters Megaclusters. Any spin can wake the Megapays feature, and staking higher shortens the odds of it landing. When it fires, a random card symbol from Ace down to Nine is picked as the Megapays Symbol, then a single locking spin pins every copy of it in place and respins around them. Four or more locked symbols pays out: four to seven the Mini, eight to eleven the Midi, twelve to fourteen the Major, fifteen or more the Mega. The jackpots only pay in real money, so a fun-money session never awards them.

Underneath that jackpot chase runs BTG's Megaclusters engine. Wins are clusters of touching matching gems, and every symbol in a winning cluster shatters into four smaller ones, so the board keeps reacting and growing. It opens at 4x4, sixteen Megaclusters, and builds toward 8x8 as reactions chain. The gems are glossy, blue, red, orange, purple and teal jewels plus green and yellow, packed into a chunky gold machine frame with a bright Vegas-jackpot shine. Two wilds share the rainbow star shape. The plain Star Wild only fills in for its neighbours and never forms a paying cluster on its own. The Gold Wild does the heavy work: each time one or more Gold Wilds help complete a win, the multiplier badge above the grid ticks up by one, from x1 with no cap, and it holds across the whole reaction run.

Free spins drop you straight onto the full 8x8 grid, up to 256 symbols at once, with that same uncapped Gold Wild multiplier running the entire round. You can buy into the free spins directly, though the Megapays jackpots stay off the menu since they only trigger off live bets. And keep the two ceilings separate in your head: the 27,050x top belongs to the base game and free spins together, while the Mega is its own euro pool with no cap at all, from Big Time Gaming.
