The main difference is that Eşli Okey is a 2v2 team game, while solo Okey is every player for themselves. In solo Okey each of the four players competes alone and a single winner takes the reward. In Eşli Okey the two facing players are partners, results are scored per team, and the winning pair shares the pot. The tiles, the okey rules and the way you finish are otherwise identical, so the skills carry straight over — you just add teamwork, played without any table-talk. Both versions use virtual chips only, with no real money and no cashout, so neither is gambling.
