Oak Games

Each round has 2 open plays. 

The first open play is after completing level 55. 

Open Play allows you to collect additional socks from levels 1 to 55, so you can complete sets and achievements.

You can leave Open Play at any time by clicking the Level Up button.

 When on levels 56 to 100 you are still in round 1, this means that you can still play with your friends that are also in round 1. 

However you will no longer receive socks from level 55 and below from the washing machine.

but you can still take and receive those socks from your friends to help them progress.

The Second Open Play is after completing level 100. 

At this point you may collect additional socks from levels 56 to 100 to complete sets and achievements. 

You can leave Open Play at any time by clicking the Round Up button.

If you do choose to progress onto round 2 then you will no longer be able to play with your friends that are still in round 1.
