I'm done with all levels except level 84 which is missing its battery so you can't complete it. Have written the author but got no answer. Otherwise, I absolutely love this game. ### 5/5 — wonderful and hard *2011-10-09* It is a good game but some levels are really hard ### 5/5 —  *2011-06-24* Fantastic app ### 5/5 — cooooool app I love it! *2011-06-24* puzzle is hard to solve. but it's very fun well-designed puzzle and UI great! ### 5/5 — Hard but fun *2011-06-19* This is something you really have to think about, and takes a bit to crack a puzzle but well worth the fun. ### 5/5 — Awesome puzzle game *2011-06-18* This is a fantastic puzzle game. If you like trainyard you should like this game as well. The game is very well done and I have enjoyed solving the puzzles so far. ### 5/5 — Awsome game! *2011-06-18* Totally recommend this! ### 5/5 — Stylish but fiendish. *2011-06-18* BULBS! puts itself in a difficult position from the get-go by being a puzzle game on a platform that is simply drowning in them, but turns out to be the definition of a stand-out. The intelligence and depth of its level design, the professional, stylish presentation, and impressive length make this one of the most worthy puzzlers on the App Store. The difficulty certainly ramps sharply after the training levels, but it's worthwhile for the satisfaction of finally getting by these sticking points. An excellent game and exceptionally well put together. Play this game. ### 5/5 — The-a *2011-05-29* I like this game it is interesting ### 5/5 — Awesome *2011-05-25* This app store tidbit is a totally original and ingenious game. It first teaches you the principles of electricity with batteries, lightbulbs, and switches... you have to get the right combination of switches to turn on the white bulbs and sometimes avoid the red bulbs. Other puzzles are like sliding puzzles where you have to slide wires into place to turn on the bulbs. My sons, age 12 and 14 are also enjoying this game. Well worth the price! A very creative mind came up with this game. Congrats to the developer or developers. ## Frequently asked questions about BULBS! ### What is BULBS!?
