The Green Machine Bingo Slot by Light & Wonder

Forget paylines and symbol pays for a moment. The Green Machine Bingo runs on a collection meter where green balls land, stick for three spins, then fade through blue and grey before disappearing. Each ball carries a value printed on its face - x1, x2, x3, x5, x10, x20, or a MINI ($10) or MINOR ($50) jackpot tag. The locked yellow STAR sitting on a red plate in the middle cell never moves and never pays on its own; it just substitutes for ball colours when the 12 win lines are evaluated.

When a line completes, the game adds up every multiplier and every MINI/MINOR value sitting on that line and pays the sum. So a five-cell line holding x10 + x5 + STAR + x2 + MINOR is a single award totalling 67x bet ($50 MINOR at $1 stake counts as 50). Then those cells clear for the next spin. There's also an Instant Win that can fire on any freshly-landed green ball, paying the value shown without needing a line at all. A neat detail: when only one cell remains to finish a line, it gets highlighted, and if a green ball drops on that spot, the entire row and column running through the intersection convert into copies of that ball at the same multiplier.

Anything passing through the central STAR is a Super Bingo line, and that's the trigger for the wheel. Wheel slices include x25, x75 or x100 of total bet, Double Win for the round, Award All (collects every visible ball's value at once), the four jackpot tiers from MINI up to the GRAND at $10,000, and a slice that throws you into the Bingo Bonus.

The bonus is where things get weird. You get 3 spins, and instead of green balls, B-I-N-G-O letter balls drop and stick. Spell BINGO and the spin counter resets to 3 while every held letter upgrades into a coloured ball worth a multiplier of total bet - bright green for 2x, dark blue for 3x, purple for 4x, red for 5x, orange for 10x after five completed BINGOs. Win lines don't matter here; only the upgraded ball values pay out when the spins run out. Any orphan letters left over get a minimum x1 so nothing is wasted.

Visually it's pure Vegas bingo-hall retro. Black bingo-ball reel backs sit inside a lime-green border with gold trim, the four jackpot meters stack down the left rail in red, blue, green and magenta plaques, and fresh balls land with a tiny lock icon to mark their persistence. It's a Light and Wonder NextGen build, so the UI feels like a land-based cabinet ported to browser - no buy bonus, no ante, no free spins in the traditional sense. The whole game is the collection meter and the wheel.
