VatRaceFlip

This is a mahjong themed game with two different game modes:

1. The first is the "Mahjong Speed Race" mode, where players need to quickly click on mahjong tiles that meet the target conditions (such as even numbers, numbers greater than 4, etc.) on two conveyor belts. Each correct click will score 10 points, and an incorrect click will deduct 5 points. The time limit is 60 seconds;
2. The second is the "Mahjong Flip" mode, where players need to find all even or odd mahjong tiles in a 4×5 card matrix. Each correct tile found will score 20 points, and the time limit is 120 seconds.
