As an AI language model, I can provide you with some ideas on how to create a game of CBT for children. Here are some steps you can follow:

1. Identify the target age group: The game should be designed according to the age group of the children you are targeting. For example, younger children may need simpler language and more visual aids.

2. Create a set of cards: The cards should represent different situations that children may encounter in their daily lives. For example, a card could say “I didn’t do well on a test” or “I got into a fight with my friend.” Each card should have a picture or illustration to make it more engaging.

3. Develop positive thinking strategies: For each card, you should develop a set of positive thinking strategies that children can use to reframe the situation in a more positive light. For example, for the “I didn’t do well on a test” card, the positive thinking strategies could be “I can learn from my mistakes” or “I can ask my teacher for help.”

4. Create a game board: The game board should be designed to be engaging and fun for children. It could be a simple board with spaces to move along, or it could be a more complex board with different challenges and obstacles.

5. Play the game: The game should be played with a therapist or counselor who can guide the child through the different situations and help them apply the positive thinking strategies. The game can be played over multiple sessions to reinforce the strategies and help the child develop a more positive mindset.

Overall, the game should be designed to be engaging and fun for children while also helping them develop positive thinking strategies that they can use in their daily lives.
