+## Additional Information
+
+- be sure to evenly assign options to values or the randomness will skew in favor of a subset of options -> it will no longer be even odds
+- if you have experience with binary numbers and binary counting, you can add or reduce the number of coin flips if needed
+- use free roll / re-roll for padding choices to ensure a propr selection list
+- it is advised / recommended to keep selection lists short to avoid fatigue caused by coming up with options to choose from
+- if creating a selection list at the time of need proves difficult, try working on general, re-usable lists when not in need of a selection list
+- if you notice you have a regular set of "go to" choices, this came can add variety to times that require a selection from the "go to" choices
+- selection list development can be a very challenging process, please do **NOT** "fight it" or "push through" or similar. even only 2 options allows the game to be played
+- if you can only think of one choice, you've likely already made a decision
+- if you can not think of any choices, please try playing the game at a later point
