# Reinforcement Learning Example | ||
|
||
Refer to [this blog](https://blog.tensorflow.org/2021/10/building-board-game-app-with-tensorflow.html) for background. | ||
|
||
### Overview | ||
|
||
This app demonstrate a reinforcement learning agent for a simple board game. It is ported from the [official Android app](https://www.tensorflow.org/lite/examples/reinforcement_learning/overview). | ||
|
||
### Instructions | ||
|
||
Run `scripts/download.sh` first to download the model and then start the Flutter app. | ||
