Fermi Time! (Math)
Uh oh! In order to properly calibrate your time machine, you need to answer a list of Fermi questions (“quick estimate of a quantity that seems difficult or impossible to determine precisely”). A close estimate will ensure that your time machine will work with no problems. Will you be able to find the answer to these problems and build your time machine?
Portal Problems (General)
You've been sucked into a rogue time portal and are trapped in the past! To navigate through twisting wormholes and return to your timeline, you must solve a series of mind-boggling challenges. The clock is ticking, and only your wits can guide you home. Can you puzzle your way back to the present, or will you be lost in time forever?
Bridge Across Time (Engineering)
A tear in the very fabric of time hurls you into the unknown, leaving you stranded between eras. To return home, you must do the impossible: build a bridge across a chasm of time. With limited materials and endless creativity, will your creation defy the laws of physics and endure the test of time, or will you be trapped forever? The clock is ticking—your future depends on it!
