The objectives of this research are: 1) to develop a game for learning SQL with a puzzle game with SQL, and 2) to evaluate performance of the development of the proposed game. The project development tools consisted of Unity and Visual Studio Code. Data collection tool is game performance evaluation form. Research methodology can be classified into 5 steps: 1) problem and requirement analysis, 2) system design, 3) system development, 4) system testing, and 5) system evaluation by five purposively selected experts. 

The findings from this research are: 1) the puzzle game with SQL works well to enhance SQL learners; they can also learn and apply SQL. 2) the efficiency of the proposed game evaluated by five experts is in highest level (=4.64, S.D.=0.44). When applied to the sample group, it was found that the comprehension score increased from the mean score before learning. representing 36.98%
