How Tumble works
Tumble helps the adult running the games (a parent, a teacher, a PE coach, a camp or party leader) pick an active game for kids, plan a whole session or adapt a game they already know. You tell ChatGPT or Claude how many are playing, their ages, where you are and what you have; Tumble answers from its own library of game cards, and only with games whose rules fit everything you said. Every game comes with clear steps, how it ends, variations and its safety lines, and in ChatGPT and Claude a card shows the game moving.
The library holds 42 games: partner push-and-pull games written by Tumble (Sumo Push-Out, Palm Push, Stick Pull, Knee Tap and more) and traditional playground and party games (Freeze Tag, Sharks and Minnows, Duck, Duck, Goose, Simon Says, Fruit Salad, Capture the Flag and more). The matching is deterministic: the same request gives the same games.
Things to ask
- Use Tumble to find a game for two kids, 6 and 8, in a small living room with nothing out
- Use Tumble to plan a 40-minute PE session for 24 third graders in the gym
- Use Tumble to pick a running game for eight kids in the backyard, with the safety rules
- Use Tumble to make Freeze Tag work for five kids in a small yard
- Use Tumble to find a calm game for me and my 4-year-old before bed
Naming Tumble ("Use Tumble to …") makes the assistant use it; without the name it may answer from its own knowledge instead.
The five tools
All five only read Tumble's game library. None of them writes anything, signs you in or calls another service.
| Tool | What it does | What it changes |
|---|---|---|
games_search (Find games that fit) | Games that fit the players, ages, space, equipment, minutes and energy you give, each with its safety lines. When nothing fits, it says which constraint to loosen. | Nothing |
games_get (Get a game's rules) | One game's full card: setup, steps, how it ends, variations, safety lines, source and licence. | Nothing |
games_plan_session (Plan a play session) | A warm-up, one or two main games and a cool-down that fit the group, with minutes that add up to the time you have. Under 9 minutes, or when only one or two games fit, it plans a main game and says why. | Nothing |
games_remix (Adapt a game) | The material to change a game toward one goal: fewer players, less space, indoors, quieter, easier, harder, more accessible. | Nothing |
games_vocab (List search terms) | The equipment, spaces, mechanics and skills the other tools understand. | Nothing |

Troubleshooting
- "No game fits." The answer says which single change would help and how many games it opens up, such as a bigger space or a wider age range. Saying "we have nothing" is different from not mentioning equipment: nothing means games that need no equipment at all.
- The assistant wrote its own game instead. Start the request with "Use Tumble to …", or pick Tumble in the app menu, so the assistant calls it.
- The card doesn't show. The answer text has the same game and rules. In Claude, remove the connector and add it again after an update, because Claude keeps an old tool list.
- A game isn't right for your group. Ask Tumble to adapt it ("make it quieter", "for a child who can't run"), or email us at support@theopenapps.com.
Physical play needs an adult nearby. Read each game's safety lines before you start, match partners by size for push and pull games, use soft ground, and stop at once if anyone is hurt. Tumble gives game rules, not medical advice.
