A simple game of combining numbers.
Multiple 1s combine into 2, multiple 2s combine into 3, what is the maximum value? Although it may seem simple, the key is to get a high score. You need to observe how to connect more numbers at a time so that you can get a high score.
Or do not combine the maximum value when it is not necessary.
Don't worry, the score will definitely be different each time.

The maximum score is difficult.
