... a set of (up to) double 21`s dominoes, and as of version 1.1 has support for triangular dominoes.
[bo|ne] [ya|rd] only supports 'typical' domino sets, i.e. sets other then double 6 must be extended by 3 (9,12,15,18,21)
With a little reworking, [bo|ne] [ya|rd] can support 'non-typical' sets, such as double 8. If you want support for such sets, let me know.
Triangular dominoes commonly come in sets numbered 0 through 5, and sets numbered 0 through 6.
