I've spent way too many hours testing browser games so you don't have to. Here are 5 that are genuinely addicting — no downloads, no sign-ups, just open and play:

1. Slope — A ball rolling down a never-ending slope. Sounds simple. You'll be sweating by level 3.

2. 2048 — The OG brain-melter. If you haven't hit 2048 yet, you haven't lived.

3. Krunker.io — A full FPS in your browser. The movement system is actually cracked.

4. Shell Shockers — Egg-themed multiplayer shooter. Absurd concept, surprisingly competitive.

5. Little Alchemy 2 — Combine elements to discover new ones. 700+ items to unlock. RIP your afternoon.

These are just the tip of the iceberg. Inside PlayNova, I'm curating the best browser games every week — from hidden indie gems to competitive multiplayer bangers.

If you're the type who needs a quick game during lunch, between meetings, or at 2am when you can't sleep — this is your spot.
