Colossal Splash: Ink & Win Slot by Light & Wonder

The orange octopus clinging to the Greek column on the left of the reels is not just decoration. He is the Ink & Win collector, and the way his value compounds is the one rule worth understanding before anything else here. Each time five inked positions fill with fish on the hold-and-respin board, he slides into the centre, sweeps up every fish value into the win meter, adds the same sum to his own running tally, then doubles whatever number he now sits on. Hit that collection twice in a single bonus and his personal value alone has doubled twice on top of the fish he just absorbed.

Getting there is a three-step trigger chain. The base game runs on a 25-line setup with the Colossal Mystery Symbol dropping a 1x3, 2x3 or 3x3 block onto reels 2, 3 or 4 at the start of a spin, then revealing a single symbol across the entire block when the reels stop. Land three or more yellow Bonus angelfish and you get 8, 10 or 12 free spins, no retriggers. During free spins the mystery blocks land more often and can resolve into mixed Value Fish (goldfish, striped angelfish, dolphin) instead of regular pays. Three Value Fish across three different reels send you into Ink & Win.

Ink & Win itself is a hold-and-respin board with only fish symbols and empty space. You start with three pink-shell lives at the top, lose one for every fish-free spin, but every fish that lands resets the counter back to three and locks in place with its cash value attached. Goldfish carry 0.5x to 10x bet, the striped angelfish run 12x to 25x, and the blue dolphin pays 30x to 50x. Two modifier fish change the picture mid-feature: the Add Fish drops a random value and then adds your current bet onto every other locked fish on the grid; the green angler Collect Fish takes the sum of everything visible and displays the total as its own value. If both land on the same spin, Add Fish resolves first.

The whole thing sits in a sunken-temple aquarium with a meander pattern across the engraved stone reel header, kelp and coral spilling around a Greek colonnade in pale blue-green water. Royal letters are carved stone covered in seaweed - green A, red K, orange Q, blue J, pink 10 - which is a more interesting low-pay treatment than the cartoon fish above them would suggest. No buy bonus, no ante, no jackpot, no purchasing route into Ink & Win at all. The 6,000x ceiling is reachable only by walking the full trigger chain and getting the octopus to collect at least twice with strong fish values locked on the board.
