Slingo Supreme combines characteristics from slot machines and bingo. Each level has a grid of numbers arranged like a bingo card, with slots at the bottom. Pulling a chain at the right side makes the slots spin and show random numbers. The first spins are free, but the last ones cost a certain amount of points. Matching slot numbers with the grid numbers makes them disappear, leaving squares with stars. The objective is to create slingos, continuous rows and columns of five of these squares in the grid, and eventually clear the grid.

16 power-ups and 8 power-up slots are unlocked after achieving certain goals, and can be selected at the start of each round. They appear randomly on both the slots and the grid, and are stored on right side of the screen: Pattern makers create a series of numbers with golden background on the grid that give extra points after being matched; Slingo vision shows the hidden power-ups behind the numbers; The nudge replaces the slot numbers with a new sequence, when no number is matched on the grid; Extra spins are used with the last spins, providing an alternative to paying for them; Cell jokers match any number on the grid; Extra coins makes money appear on the slots, giving more points; Mystery chests either double the points, or cut them in half; Devil protection maintains the score intact from the encounters with the devil; Multipliers increase the score by multiplying it to the sum of their accumulated instances; Power shots clear the squares surrounding it; Instant slingos match a whole row or column; Bouncing slingos increase the number of possible slingos on the grid, from 12 to 24. Two types of jokers appear on the slots, one matching any number in on the column above it, and the other matching any number on the grid.

The devil appears on the slots three times in each round, bringing up one of its five mini-games where the player has to gamble a quarter, half or all of the score. Most are chance games with cards, but some require skill, requiring precise timing to hit the button at the right time to win a coin toss or paying close attention to the moving cups in the shell game.

Two extra modes become available after playing the Supreme Mode. In the Classic Mode, there are no power-ups or devil mini-games. In the Daily Challenge, there is a different goal to be achieved that changes daily.
