WaterBlox Gigablox is a 6-reel, 6-row, 50-payline slot. It appears to be a square grid slot, but it is not. You win when three, four, five, or six identical symbols appear in a row, starting in the first reel and moving clockwise. Click the "bet" button below the reels to play from 0.20 to 50 per spin. This displays all 17 betting/staking possibilities.
The low-paying symbols are standard card suites that look like cans of fish. The high-paying animal symbols follow these symbols. The octopus pays 10x the wager for a fully covered payline, followed by a frog, a pufferfish, and a purple fish. The wild symbol, a yellow anglerfish, replaces pay symbols. A potion scatter can activate free spins.
Water Blox features Yggdrasil's Gigablox feature, wandering wilds, respins, and a Monster Free Spins. Gigablox are large 2x2 to 6x6 symbols. They occur on any reel and are evaluated as 1x1 tiles for wins.
A random number of base game symbols (anything from 1 to 3) will go wild at the start of a respin. After a win, a respin moves the wilds to a random position. 1x1, 2x2, 3x3, 4x4, 5x5, or 6x6 blocks create 1, 2, 3, 4, 5, or 6 roaming wilds, accordingly. A roaming wild turns a large block into a wild during the respin.
To activate Monster Free Spins, you must first land at least five scatter symbols during the main game. Any scatter that lands in the bonus round awards an extra free spin. Every free spin activates the Wild Respin feature, which turns 1-3 random symbols into wilds. Each wild symbol also adds a point to the metre. Collecting 20, 45, 75, or 125 wilds doubles the win multiplier to x2, x3, x5, and x10. Every collection level grants +2 free spins. Remember respins don't collect wilds.
