Hint: I needed 2 reactors and I placed 2 storage tanks (pipeline) between them.

Thus, create reactor1 with double through-put. Hint: Use CTRL+mouse to duplicate all marked symbols. Hint: You need to use CTRL-switches! - Use 3 CTRL-switches to steer and split gas flow. Reactors/Waldos are used here to steer gas flow into the 3 tanks**. You should time the explosions so that they take place when the mining robot's wheels are next to the tanks. Task: You must direct methane into special tanks**. In this assignment an automatic mining robot is on the loose and about to crush the base. Task: You have to fix backwater jam! - Hint: You need to largely extend pipeline length between reactor 1and3 and between reactor 2and4. This one is tricky and difficult! - Hint: Use reactor2 to unbond CH 4 to CH and 3x H. Hint tip: I needed 1 Sync each, for red cycle and blue cycle. Hint: Use 1st reactor to unbond CH 4 to CH 3 and H. This is the third planet and it introduces a few more concepts. I needed 1 Sync each, for red cycle and blue cycle. Hint2: Waldo2 grabs and moves Carbon between the previous two H, bond, HCH to output area. Hint1: Grab and move 1st Hydrogen, drop it 2 grid squares to the right. Hint_tip: You will need only 1 Waldo loop to do all this and to move HCl to output area. Grab Hydrogen and move it next to Chlorine. In production assignments you can build several reactors and decide the connections between them freely, provided that in the end the correct molecules end up in the correct places. This one, however, is a Production assignment.

Until this, all assignments have been Research assignments. This is the second planet and it introduces a few more concepts. Collisions are to be avoided - empty waldos can collide with each other, but atoms cannot. This puzzle requires you deposit the relevant input atom into the correct output location. This puzzle requires you to simply input the H2 molecule and then drop into the output area. This can be completed easily by following the on-screen tutorial

Some, but not all, of which have tutorials. This is the first planet of the game and contains the introductory levels.
