Mahjong is one of the most popular Chinese tile games played in Japan. Mahjong-related seizures (MRS) are rare praxis-induced seizures. We identified three patients with MRS from February 2000 to February 2021. ⋯ They did not have features linked to idiopathic generalized epilepsy. All patients were seizure-free after behavioral adjustments, although one patient required anti-seizure medication and avoided long duration games. These changes may help other patients with MRS continue playing Mahjong.
