When you start your order on PlaytestCloud you will be asked if you want to test a New Game or a New Version.
When you first start playtesting a game on PlaytestCloud you will want to select New Game. From here you can name it and give the playtest it's own custom name. The game name for example could be New Racing Game and the playtest could be called Tutorial A – FTUE or Art Style 01 Concept test.
When the time comes to test your game again you'll probably want players who have never tested your game before. In this instance you would select New Version. This will exclude people who have previously participated in playtests for the selected game on PlaytestCloud.
Using the same example as above you would now select New Racing Game from the dropdown menu and the playtest could be called Tutorial B – FTUE.
