board game for 9yo boy

[nobalance]

Any recommendations? Preferably under £10
Thanks!

Not all under £10 but close - my 9 year old (admittedly slightly geeky!) likes:
qwirkle
rush hour
scrabble (currently half price at a tenner on amazon)
labyrinth
pass the pigs
:)

Thank you, good suggestions. Not heard of qwirkle - sounds fun just from its name!

Monopoly
Cluedo
Chess

Monopoly is still the favourite
