DIAMOND RAINBOW™ by Kadon

24 diamond-shaped tiles and 6 triangular tiles carry the 6 dominant rainbow colors in every combination (one sample shown at right). Join them so colors meet only their own shades or their neighbors in the spectrum. Patterns emerge as you rearrange the tiles. Illustrated booklet shows many interesting shapes to solve outside the 8½" tray, as well. It's proven to be one of our instant hits for all ages, 5 to adult. All acrylic, for 1 or 2 players.
