I recently came across a sports prediction platform called WinNova. I did a quick test, and there are a few points that I find quite interesting.

Before placing an order, it provides an AI analysis, which is not some mystical recommendation but rather a data-driven perspective. For those who don't want to rely solely on intuition, it can be somewhat helpful.
Additionally, it supports copy trading from other addresses, which is quite friendly for people who are "lazy to research odds but still want to participate." You can see how others are doing and then decide whether to follow.
The gameplay is also quite flexible, allowing for free parlay combinations. It uses Polymarket's liquidity at the core, and the overall logic is more like a prediction market, so it's not unfamiliar to those who are used to that.
The chain is on Polygon, and all transactions are on-chain and transparent, which is well handled.
New users get fee-free trading, and registration has no barriers. I’ve only tested with small positions so far, but overall, the learning curve isn’t high.
If you're interested, you can check it out yourself:

If you use my link, it seems the first 20 users get a 3 USDT trial fund, which is a decent way to test the waters.
Remember to control your positions and take it slow for better safety. DYOR
