- Read the on-screen prompts once. Most casual games explain their entire control scheme in the first ten seconds and never again.
- Spend your first attempt learning, not winning. Poke at everything on screen; browser games hide small mechanics in plain sight.
- Set a small goal per session — one level, one upgrade, one new best — and stop when you hit it. It keeps the game fun.
- Because this is a Educational game, say the answer out loud before you click; it makes the learning stick.
