What happens if i delete iCloud from iPhone?

I have 4s if I select my iCloud account and I have backup games in the account can I redownload them if I sign back in will the games be at the same lvl I left before deleting the account. And another thing if I use another account will I start like new when I download a game I played on my iCloud account and will it affect my phone service

ICloud usually stores data of Contacts, Calendars, reminders and safari data. So when you go for deleting the iCloud account it would ask you to confirm whether to delete the data and once you confirm all data is lost. You may go with steps to recover account, but before deleting its best to backup data on pc.

Connect your iPone to your pc and take a backup of it and you can restore it anytime
