Joker series: how Joker Ra turned toward hold and win
Egyptian imagery, fruit symbols and a grinning joker first converged in Endorphina's Joker series through 2023's Joker Ra, where 100 paylines and expanding symbols set the original rhythm. Its 5x3 layout, medium volatility, 3,000x maximum and gamble feature combine classic line play with an ancient-Egypt frame rather than building the game around a large bonus system.

Joker Ra: Sunrise recuts that foundation around fewer paylines and sharper bonus pressure. The grid and 96.07% RTP stay unchanged, but the line count falls from 100 to 25, volatility rises from medium to high and the maximum increases from 3,000x to 5,000x. Free spins, multipliers, respins and Hold and Spin give Sunrise distinct bonus states, so the sequel concentrates more of its risk outside ordinary line wins while retaining the Egyptian joker and gamble option.
