Snapchat decided to remove Alphabear Hustle from the Games drawer on or around 2022-04-11. We assumed that people who had already played it could still keep playing it. Initially that was not the case, but about a day later it was playable again by players who had previously played it. They were able to access it by pulling up a recent conversation in which it was played and launching the game from that conversation. We hope that the game remains available for a long time to come.
Since Alphabear Hustle will no longer be in the Games drawer, you might want to keep handy a conversation from which the game was launched. Then you can launch the game by pulling up that conversation and launching from there (for so long as the game continues to be available).
Alternatively, if you open this hyperlink on the device where Snapchat is installed, it should launch the Snapchat app and bring up the game within the app: https://snapchat.com/games/alphabear
