Oh, I am so excited to share this with you!Today, I’m going to show you how to create a personalized, professional-looking board game in literally one step using Gemini’s Nano Banana 2. Easy and Free.

Step 1: Let Gemini Build the Content
Go to Gemini- which is Google’s primary AI assistant- and register for free. Then, ask Gemini to generate the questions you are going to use. For my B2 students working on “Sport” vocabulary, I need short, punchy questions that will actually fit inside a game square.
Step 2: Creating the Board Game
We are going to use Gemini’s image generation tool (the famous Nano Banana) to build the entire board—questions and all—in one go.
- In Gemini, go to Tools,
- Select Create Image, and if you want the highest quality, don’t forget to
- Select Pro (you get 3 of these a day on the free plan!).
Prompt:
Create a printable board game with a winding path of [20] squares. (Board game race style) in English about Sports. Each of the squares will contain one of the questions generated above. Scrupulously respect the spelling of the questions without changing any letters. The questions cannot be repeated in the game. Include a ‘Start’ square at the beginning and a ‘Finish’ square at the end. All squares are connected to each other in sequence. The squares are not numbered. Colorful design. Put each of these questions in a square and respect the spelling without changing any letters. Title it ‘SPORTS’ and under the title ‘Created by www.cristinacabal.com‘. Everything must be in English. [Hand-drawn sketch] style.”
Important: Sometimes, and especially if your questions are too long , there could be some minor spelling errors. Remember that we are using a machine here. If this is the case and you don’t want to generate the speaking board again, there is something you can do to fix these errors. Go to Canva, upload the image, click on Edit and Grab text to modify it.
And now, the most important thing: HOW TO PLAY.

Put students in groups of three and handthem a standard small die and three individual counters. They roll the small die to navigate the board. When they land on a square, that student has to speak about the topic for exactly three minutes.
Enter “The Grammar Dictator”
Three minutes of fluency practice is fantastic, but I want to push their grammatical limits. Wanna add to the fun? Use a giant foam dice to dictate how they must answer the square they selected.
How? You simply assign a grammar rule to each number on the die and write it on the board
-
Roll a 3? They have to build their 3-minute argument including the connector of contrast Despite
-
Roll a 4? They need to include a perfect modal.
