HOW TO PLAY

How to play Observatory Shift

Six nights beneath clear skies Each night has 3 time units. Choose one of three open tasks; any geometry category fits any night. A task takes 1 or 2 units and awards its printed points. A new task appears from the fixed sequence after each choice. Skip to the next night whenever you want; unused time is lost. Reach 24 points by the end of six nights or when every task is placed. The finite sequence contains ten original tasks.

Controls

  • Keyboard: press 1–3 to choose an open task. Press Enter on the page or the Next Night button to skip tonight. Z undoes one action; R resets the whole shift.

Tips

  1. Fit a 1-unit task into a 1-unit gap. Skipping to the next night discards unused time.
