Devices to make points on cart (12)

I believe the answer is:

contraptions

'devices' is the definition.
(contraption is a kind of device)

'make points on cart' is the wordplay.
'make' is an anagram indicator.
'points'+'on'+'cart'='pointsoncart'
'pointsoncart' anagrammed gives 'CONTRAPTIONS'.

'to' is the link.

I've seen this clue in The Irish Independent.
