Light it up

Good math skill game, though sot of misleading re use of resistors in a lighting circuit. Resistors are not rated by voltage, but by ohms (and to lesser extent, wattage - which simply specifies the amount of current which may pass through it). In real life, the larger the secondary resistance in the series circuit, the dimmer the lamp.

That said, I'm enjoying the game and think it would be great for kids. Learning about circuits is darn important.

Fun app

I want to learn about electronics and found this app. It helps learning the symbols found in schematic.

Super fun game, not maintained

I loved this so much. My son found a game like this through his school so I reinstalled it on my phone to show him. Unfortunately it does not run on iOS 14. The scaling is off and I wish I could recalibrate the input in app so I could play it again. PLEASE FIX THIS FUN GAME!
