This Rube Goldberg contraption has a twist: it contains four time machines. Schedule the arrival of time travelling elements to create a consistent loop and avoid paradoxes.

How to play: Drag one of the 4 highlighted elements into a timeline slot (on the right column) to schedule something arriving from the future at that time (an object can appear in several slots). To win, create a consistent time loop, where everything received from the future is correctly sent to the past.

I find the answer by accident I'm so mad and dumb

still a 8.5/10


...Paradoxes are not real, I loved the game anyways! But what if...


Cool game! It took me a while to solve but it totally worth it :D


Was losing my mind not being able to get this done, but I got there, and now I can sleep in peace! Darn you developer for making this challenge! Great game!


i feel smart after finishing this, good game, but maybe add tutorial or easier level for introduction


Cool game! Short, but fun.


A demo would help me a lot with this game. I'm not entirely sure what to do.

You can drag&drop some of those items into the timeline on the right. Then start it and stuff happens. The goal is to not have paradoxes at the end.
