All coins on https://pool.rplant.xyz/ are cpu mineable.
Just download there cpu-miner software and you can get a lot different coins to mine.

Myself I'm focusing on Roi-coin (cpu-only). The current payout is pretty high atm. But the prices are a bit low. But the coin has a triple hybrid feature which also allows it to be staked. So I am staking the mined coins till prices rise back to at least 8 Satoshi.
