Game of darts from time to time eclipsing anything (8)
I believe the answer is:
draughts
'game' is the definition.
(draughts is a kind of game)
'darts from time to time eclipsing anything' is the wordplay.
'from time to time' means one should take alternating letters (letters removed on a regular basis).
'eclipsing' means one lot of letters goes inside another (eclipse can mean to cover up or hide).
'anything' becomes 'aught' (I've seen this in another clue).
The alternate letters of 'darts' are 'drs'.
'drs' placed around 'aught' is 'DRAUGHTS'.
'of' is the link.
(Other definitions for draughts that I've seen before include "Board game with huffing" , "Board game for two" , "They may make people cold" , "Windows-supplied, pain-in-the neck- inducing" , "Traditional board game" .)
