Sorting frogs

Frogs scattered all over the logs, you need to collect 4 identical frogs on the same log. To do this, click or tap on the desired log to select the desired frogs, they will be highlighted. Next, click on another log on which you want to move the frog. If the conditions are met, the frog will jump to the new location. When 4 identical frogs gather on the log, they will run away and you will get a reward.
