Mega Ball

Mega Ball combines bingo-style cards with a live ball-drawing machine.

Cards. Cards are bought before the draw in sets of 1, 10, 25 or 100, up to a maximum of 400 cards.

The draw. A custom ball machine holds 51 balls, and 20 are drawn one by one in each round. Numbers on a card that match the drawn balls are marked. Each card has up to 12 possible lines, and the more lines completed, the larger the payout.

Mega Ball. After the main draw, a further ball, the Mega Ball, is drawn and an RNG multiplier between 5x and 100x is generated. If a card completes a line with the Mega Ball number, the payout for that line is multiplied. A round can include one or two Mega Ball draws.

The numbers. At launch, Evolution said multipliers could raise payouts to up to 1,000,000x the bet. It lists the game as available on desktop, tablet and smartphone.
