Let it run. Experiment and learn. There are many levels. Some may seem really difficult. Do not be discouraged. Be creative. This game is very, very fun. It is appreciated! ### 5/5 — Thanks! *2024-02-18* Build a machine. Let it run. Experiment and learn. There are many levels. This game is very, very fun. It is appreciated! ### 5/5 — Reminds me of the Golden Age of Apps *2023-12-27* This is a must-have for fans of Fantastic Contraption. The fact that this game has no ads, no in-app purchases, and no data collection is almost unbelievable. This should be on the front page of the App Store, not another anime micro-transaction simulator. ### 5/5 — My favorite game ever *2023-09-01* I never write reviews but I love this game so much. I wish there were even more worlds. I like that you can build whatever u want. I’m pretty sure the star system is based on time. I wish there could be different modes to achieve 3 stars in, like least time, least materials, most materials, etc. very fun I enjoy this very much. ### 5/5 — Wish there were more levels it’s so fun *2023-08-01* Really enjoyed this. It’s a lot like one of my favorite computer games, Fantastic Contraption. Stars are based on how fast you can get the solve by the way. ### 5/5 — This game is fantastic! Deserves more spotlight. *2022-12-20, version 1.4.0* Me an others I've shared this with are enjoying the heck out it. Quite a diamond in the rough. Hopefully more people that enjoy it will pick it up and give it a shot. The interesting and creative ways to solve the puzzels are endless and sometimes comical. Share it with a friend. ### 5/5 — Great game *2022-11-27, version 1.4.0* This game is very well built and with no ads! A serious challenge but the parts are powerful and the possibilities are endless. More levels please!! As some have mentioned, I’d like a clearer explanation of the star system - it seems to be based purely on time but the the goals are not explicit. Also an explanation of the parts - it seems like dotted lines are both transparent to the ball AND lighter? But I’m not sure. Another feature that would take this game to the next level is being able to see how other people solved the same level after you complete it, or maybe after you get 3 stars to preserve the challenge. Right now it shows rankings but I want to be able to see everyone else’s creativity. Great game!! ### 5/5 — Hints for this great game *2022-07-10, version 1.4.0* Do not give up. Combinations of wheels, chains, rafts, catapults and arms/paddles will help with obstacles. Time as in speed appears to be the criteria for more stars. This continues to be the most enjoyable game I have recently experienced. Thanks very much! ### 5/5 — Absolutely incredible. *2022-06-16, version 1.4.0* One of the greatest iOS games out there, period. Here’s a vote for more worlds please! ### 5/5 — Catapult *2022-06-12, version 1.4.0* Fantastic. I am wondering if some more unique components could be added beyond the basic components available, perhaps in later levels! To give it more of a unique twist from fantastic contraption. Thank you for the game. Also, tip for those who have trouble - make a catapult. Attach a long rod to the edge of a wheel. ## Frequently asked questions about Grejsimojs ### What kind of game is Grejsimojs?
