Abstract: The purpose of this pilot study was to rank commercially available digital math games for selection in a larger future study of digital math games developed for 6th-8th grade students. This paper reports on the results found from playing and ranking 761 commercially available games based on four effective general and seven mathematics-specific criteria (four of which are hypothesized to be essential). Overall, the findings suggest that, while there are games for each grade level that have the four effective general criteria, it is very difficult to find games that also have the four essential mathematics-specific criteria of simultaneous linking (SL), creative variation (CV), focused constraint (FC), and guiding feedback (GF). Of the 17 out of 761 games that ranked high on the four effective general criteria, only four were coded for SL, six for CV, six for FC, and four for GF. None contained all four. Implications for the larger future study are discussed.
