The Sonic XG Android port on Jolt in 2021 was a classic example of “ambition over stability.” When it worked, it delivered some of the best 3D fan-made Sonic action on mobile.

Otherwise, stick to official Sonic games or more polished fan engines like Sonic Robo Blast 2. sonic xg android game jolt 2021
