Understanding the 76.9% vs 99% RTP
Mega Joker's famous 99% RTP — the figure NetEnt publishes on its official game page — only applies when winnings are gambled through Supermeter mode at the maximum bet. If you simply collect every base-game win, the theoretical return drops to roughly 76.9%, well below the online average.
In other words, the game's return is decided by how you play it: routing wins through the top reel set at the 200-coin stake is what pushes the RTP toward its 99% ceiling.
Supermeter mode and the progressive jackpot
After any base-game win you can bank the coins or transfer them to the Supermeter and spin the top 3x3 reel set at stakes of 20, 40, 100 or 200 coins, with a top Supermeter prize of 2,000 coins. Jokers landing in the top game trigger mystery coin wins.
On top of the 200x-bet maximum regular payout sits a progressive jackpot, awarded on a randomly selected round with its size proportional to your stake.
A true old-school fruit machine
The layout is a dual 3x3 reel set with 5 fixed paylines, and stakes are fixed at €1 or €10 per spin. Hit frequency is a lean 17%, so despite the fruit-machine look this is a spiky, high-variance game — the antithesis of NetEnt's low-volatility Blood Suckers.
