The same ones I'm playing with in the game (8)
I believe the answer is:
dominoes
'the game' is the definition.
(dominoes is a kind of game)
'the same ones i'm playing' is the wordplay.
'the same' becomes 'dom' (I can't justify this - if you can you should give a lot more credence to this answer).
'i'm' becomes 'i' (I've seen this in other clues).
'playing' indicates anagramming the letters.
'ones'+'i'='onesi'
'onesi' anagrammed gives 'inoes'.
'dom'+'inoes'='DOMINOES'
'with in' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for dominoes that I've seen before include "Table-top game" , "Game with twenty-eight pieces" , "Mistakes" , "Number-matching game" , "Game played with black pieces with white spots" .)
