This is a very fun and interesting casual game. There are four difficulty levels for you to play. The gameplay is simple, but later levels will become increasingly difficult for the player. Additionally, new species will appear on each next level. For example, the special species flame will clear the merged area of ​​any existing species. Click the next action type above to swap left and right. You can switch species types by swapping the leftmost action. Click on the empty area of ​​the merged area to move the selected species type to the specified position. If there are species of the same type above, below, left, and right of the location, it will spread in four directions to find species of the same type. If there are more than three species of the same type, they will be merged and upgraded to a new species. Repeat merging until the position cannot be merged. If the new species merged at the same time is the target species type, the game is won. If the merge area is full and the specified target species is not completed, the game fails. Properly arranging merge locations and freeing up locations by eliminating unnecessary species through fire can help you beat levels faster.
