"合成小芝麻" is the sequel to "Merge Big Watermelon," offering a reverse gameplay from big to small. Despite causing initial confusion for those accustomed to the watermelon game, it becomes addictive. The game involves combining various items in a specific sequence, such as half watermelon plus half watermelon equals coconut. Players have expressed enjoyment with comments like "Small sesame seeds are more fun! Better than big watermelon!" The game introduces a new item, sesame seeds, to the existing 11-item sequence from the watermelon game, adding an extra challenge. Tips for high scores include rearranging fruits by weight, utilizing collisions for better merges, and maintaining a size order. Beginners can easily achieve high scores using a simple sorting principle from small to large in one direction.

In case of mistakes, players can rectify by waiting for the same fruit type to appear for a larger merge. After merging a green-skinned watermelon, players must strategically adapt to the available space for continued success, adjusting the sorting direction accordingly.
