Description
This is a game app that challenges your observation, mathematical skills, and spatial imagination abilities. It includes three gameplay modes:
1. Observe the arrangement pattern of each row of playing cards and identify the missing cards in each row.
2. The result of the formula composed of each row of playing cards and operators is the same. You need to infer the formula result and fill in the missing mahjong tiles or operators in each row.
3. The original playing card matrix is transformed into the target matrix through rotation and flipping, and you can use your imagination to find the missing card in the original playing card matrix!
