Mega Joker features a Supermeter mode that is played in the top reels. Players are automatically transferred to the Supermeter mode when they win in the basic mode. The winnings in basic mode are added to the Supermeter credit that is displayed in the middle of slot. Supermeter mode play: Players can bet with 20, 40, 100, or 200 coins in the Supermeter mode at pre-selected coin value. Players can collect Supermeter credits and transfer it to the basic mode at any stage. Supermeter mode payout: Depending on the current bet, Supermeter wins are paid according to the highlighted paytable. The maximum win in Supermeter mode is 2000 coins.

Mega Joker awards mystery wins at various bets. The mystery win amount depends on position of jokers on the reels and the current bet. For example, at bet 100, a joker in the middle reel gives a mystery win between 100 and 2000 coins.

The game features a progressive Jackpot, which is awarded on a randomly selected game round. The current amount of the Jackpot is shown in the Jackpot display box. The Jackpot value increases each time the basic game is played. Once the Jackpot is won, other active players get a pop-up message that another player has won the Jackpot.
