You obviously need lightweight wallet. So software wallets with full validation like Bitcoin Core, Armory, mSigna are disqualified from the start.
Next, do you need wallet for PC or mobile device? For PC I recommend Multibit HD or Electrum, for Android/iOs breadwallet.
The only online wallet I would use for gambling is blockchain.info - whatever you do, don't use Xapo for gambling - it is against their ToS.
I need a wallet for pc laptop.
So would blockchain be the best for me? it seems the most suggested.
Or do i try Multibit HD or Electrum.
Also do these wallets come with a way to sell? or do i have to find a website?
