I'm a little stuck... Click here to teach me more about this clue!

'entry method for pools?' is the definition.
I can't tell whether this defines the answer.

'call end to lottery and fail' is the wordplay.
'call' becomes 'bell' (bell can mean a phone call).
'end to' indicates one should take the final letters.
'and' is a charade indicator (letters next to each other).
'fail' becomes 'flop' (flopping is a kind of failing).
The final letter of 'lottery' is 'y'.
'bell'+'y'+'flop'='BELLY-FLOP'

'in' is the link.
