• Clear payline indicators running horizontally across reels
• Simple paytable accessible via dedicated button
• Classic symbol sets with high visual contrast
• Minimal animation focused on winning combinations

Popular examples include NetEnt's Mega Joker and Play'n GO's Fire Joker, which modernize the classic format with enhanced graphics while maintaining the traditional three-reel structure.
