These bingo games are designed to be relatively quick. Have students draw up a 3x3 grid on some spare paper and select 9 animal names from the slides. Each time, you can change what configuration is needed to score a bingo eg. W-shape/X-shape instead of just filling the grid or 3-in-a-row.
To start the game, press the 'Shuffle Animals' button and that should randomize the slides. This means you can play several games in a row and have the animals called out in different orders each time.
Feel free to use this as a template and change the topic to whatever you want. I've included instructions on how to edit the powerpoint to shuffle fewer or more slides. Might come in handy if you're using an 'ALT laptop' like me which is all in Japanese.
