Walmart offers the Bloxels Build Your Own Video Game for $20.99. (For Prime members only, Amazon has it for the same price with free shipping.) Opt for in-store pickup to dodge the $5.99 shipping charge. That's the lowest price we could find by $8, although we saw it for $1 less in January. It includes eight different colors and 320 blocks to use on the gameboard which connects to the free Android or iOS app to build playable video games.
