Chơi nối từ không is a free word game developed by Hetpin for the Android platform. The objective of the game is to find a new word starting with the last letter of the word provided by the computer. For example, if the computer provides the word "đi học", the player has to come up with a word starting with the letter "c" to make a new phrase, such as "công việc".

The game has two modes: "Endless Play" and "PvC". In "Endless Play", the computer provides random words for the player to answer. For every correct answer, the player earns one point. The objective is to score as many points as possible. In "PvC" mode, the player's answer also becomes the question for the computer. The game continues until one player cannot come up with a new word, and that player loses. The difficulty level of the game depends on the creativity of the player.
