Free spins can trigger more free spins, up to a total of 600 free spins.

Only after all balls are drawn is the win calculated for a free spin.

This process shall continue until no additional numbers drawn match a number covered by a painting.

If an extra ball matches a number in a painting, the player shall win two more balls.

These extra balls are represented as gems, a different color gem for each painting.

Free spins shall play like initial spins, except if a ball drawn matches a number in a painting, then the player shall win two extra balls.

For example, the maximum free initial free spins would be 12×3 = 36.

The number of initial free spins in the bonus game shall be the product of the number of illuminated tiles among the three paintings and the number of paintings entirely illuminated.

Free spins shall be played with the same number of picks and bet amount as the initiating spin.If the player covers all four panels of any painting, then he shall play the free spin bonus game.Any multiplier won is in lieu of the 1x multiplier he gets for not earning any multipliers.If the player wins more than one multiplier, the multipliers are added.If exactly three of the four panels of a painting are illuminated, then the player shall win a 2x multiplier.The player shall be paid based on how many numbers he chose and the number of catches.If a number drawn by the game matches one covered by a painting, then that panel of the painting shall be illuminated.If a number drawn by the game matches a number chosen by the player, then it shall be known as a 'catch.'.The game shall draw 20 numbers, without replacement, from the range of 1 to 80.

The player may also choose to let the game choose these regions randomly. These squares will be marked with four-panel paintings, one number per panel. The player will select three 2x2 regions on the field of numbers that do not include any numbers already picked.The player may also choose to have this step done randomly. After making a bet, the player picks 2 to 10 numbers from the range of 1 to 80.In the bonus round, the player gets free spins in which catching numbers on the paintings wins extra balls. The player can win multipliers and a bonus round if enough tiles of a painting are covered. In addition to the usual spot keno rules, the game places there 2x2 paintings on the field of numbers. I first noticed it in 2021 at both and Resorts World in Las Vegas.
