Threw dice, even to get proof (8)
I believe the answer is:
evidence
'proof' is the definition.
(I've seen this in another clue)
'threw dice even' is the wordplay.
'threw' indicates anagramming the letters (I've seen 'throwing' mean this (letters get thrown around)).
'dice'+'even'='diceeven'
'diceeven' is an anagram of 'EVIDENCE'.
'to get' is the link.
(Other definitions for evidence that I've seen before include "Facts on which to establish verdict" , "Data" , "Information leading to proof" , "Information to help form a conclusion" , "Indication" .)
