Board games are one of the learning media to increase student interest in a subject. And on this occasion I made "Domino Match". And to determine the material to be applied I did it to a high school (SMA). Based on interviews with two material experts at the school, I know that the material is quite difficult for the students there, namely the Matrix. So I apply the matrix material to a game in the form of domoni cards, with the hope that their interest will arise and their perspective on Mathematics.  The selection of game tools in the learning process can be adjusted to the characteristics and needs of these students. Then in designing or making a game tool in general based on criteria that are in accordance with the cognitive development of students. Based on the results of the research there are 4 (four) factors that affect the low student learning outcomes, namely, the lack of student interest in mathematics, lack of student concentration during the process learning, low understanding of student concepts, and lack of student discipline. 

Since the introduction of ChatGPT as artificial intelligence and its massive development over the years, it has had a huge impact on various aspects of life, and it is increasingly visible in the presence of increasingly advanced features, functions, and appearances. Its use in the field of education has not escaped the advancement of artificial intelligence. For some teachers and students, the term artificial intelligence is still very new, as is its use in the teaching and learning process. Currently, Indonesia's use of artificial intelligence faces numerous unavoidable obstacles and challenges. However, in global education, it is becoming increasingly common to use artificial intelligence in the teaching and learning process. The introduction of artificial intelligence to junior high school students is considered very appropriate because students' psychology at this level is more developed, and the learning load begins to increase compared to the elementary level.
