The game skill of crossing the river by feeling the stones is to observe the river, choose the right stones, pay attention to the time, make plans and practice the reaction speed.

1. Observe the river: Before starting the game, observe the width and depth of the river and the size and shape of the stones. This will help you make a better mobile strategy.

2. Choose the right stone: In the game, some stones can cross the river more easily than others. Therefore, you need to carefully choose which stones should be moved across the river. Generally speaking, larger stones are more likely to cross the water surface, while smaller stones are more likely to get stuck in the water.

3. Pay attention to time: In the game, each round has a specific time limit. So you need to complete as many stone movements as possible within the specified time. You can try to move more stones in a shorter time to improve your score.

4. Make a plan: Before the game starts, you can make a simple movement plan. For example, you can move the bigger stones to the other side of the river first, and then move the smaller stones one by one. This can help you use your time and space more effectively.

5. Practice reaction speed: In the game, you need to make a quick decision and take action. Therefore, it is important to practice your reaction speed. Playing more games can improve your reaction speed and hand-eye coordination.
