Recently, I won a Twitter competition from Green Board Games and they sent me this Alphabet Squiggle on-the-go for my children. This is the travel size edition.

It is very simple to play by spinning the wheel then writing the letter on the pad (in upper or lower case). Then you simply create a word or picture from that letter. It is fun and easy to play.
The educational aspect of the game has been really good and I feel my children have learnt from playing it especially Ms. C as she is just learning her alphabet. I love how small and handy this travel size edition is.
Disclosure: We won this through a competition.
