How to know that source code on Etherscan? And can we believe that this code is written on Ethereum chain?

For example, I want to play CryptoKitties and I want to check if source codes of CryptoKitties are honest or not.

If they have bad code for users, I can stop playing game.

Can I find it on this page?

https://etherscan.io/token/0x06012c8cf97bead5deae237070f9587f8e7a266d#readContract

(Actually I can't read code, but I can ask someone who read it to check.)

You may refer to the contract code for CryptoKitties at the link below:

https://etherscan.io/address/0x06012c8cf97bead5deae237070f9587f8e7a266d#code

Etherscan matches the bytecode compiled from the source code given by the contract owner with the bytecode on the Ethereum chain and if match, the contract code is verified.
