So sorry, but we don't sell individual Coding blocks separately.
The blocks needed to play all three Coding games (Coding Awbie, Jam and Duo) are sold as a trio in the Coding Family Bundle.
If any of your blocks got lost or damaged (or if any of them were missing or defective upon receipt of your order), please submit a replacement request.
Note that you no longer need physical Coding Duo character tiles to play Coding Duo. However, you do need all the blocks in the Coding Family Bundle to play it.
Find more information in this Coding Duo article.
