Would - shape dominoes (or dominoes of shapes) be dúradáin cruthanna or dúradáin i gcruthanna?
and similarly - number dominoes would that be - dúradáin uimhreacha?

I assume ‘number dominos’ would be those little domino bricks with one to five (six?) dots on them … but what are shape dominos?!

Always wait for at least three people to agree on a translation, especially if it’s for something permanent.

My translations are usually GU (Ulster Irish), unless CO (Standard Orthography) is requested.

No, these are dominoes I make for language teaching - the numbers are spelled out ie not in figures and shape dominoes are dominoes which show shapes on them - cearnóg, ciorcal, triantán, ubhchruth, dronuilleog. Though I would like to know how you would say a heart-shape and a star-shape.
In fact, looking through my archives, I've found an email from le Centre Culturel Irlandais which gives me - dúradáin daite and dúradáin uimhrithe.
They also gave me this translation for what I put on the box -
one is red - uimhir a haon, dearg
two is blue - uimhir a dó, gorm
three is green - uimhir a trí, glas
four is orange - uimhir a ceathair, oráiste
five is yellow - uimhir a cúig, buí
six is purple - uimhir a sé, corcra.
but could this be put another way? is a haon dearg é - perhaps?
The other themes for the dominoes I make are textures, animals, fruit, patterns, directions and so on.

Heart (shape) hart
Star (shape) réalt (also réiltín)


Not with the copula in this case, Franc. The colours are adjectives, and the maoluimhreacha (a haon, a dó, etc.) aren't nouns on their own, hence the need for uimhir. The two ways I would expect are:

Tá uimhir a haon dearg, etc. "No. 1 is red," etc.

or

Tá dath dearg ar uimhir a haon. "No. 1 is red," etc.

Await confirmation or correction ...

I was stumped by the term, also. Not sure about British or Irish English, a fhrainc, but in American English we would usually call those things "flash cards" (as in cards that you flash in front of you, or someone else, as a learning tool), even if they were done as dominoes rather than cards. I doubt the term "shape dominoes" would be understood at all in North America.

Dia duit,
no they're definitely dominoes and designed as such for playing that game - divided into two sections with two pictures or two words on each domino. I do make flash cards too where obviously there's only one picture or word being displayed.
I have used letters taken from either the standard 'celtic' seancló lettering that you see on Irish pub windows but is also used for other languages such as Breton or the older script found in 'Everything Irish' by Annmarie O'Grady (O'Brien) - just using the outline of the letters so that the word dearg is coloured in red for example.

I have only heard 'hart' in relation to hearts in cards. I would have thought croí for the shape (also the organ). Please someone tell me I haven't been using these wrong for years.....! Or I will be very disHEARTened.......

I'm guessing it might be - cruth croí

It's hart (genitive hairt) when playing cards - check out what I've posted for playing card games under cluichí.

And I misunderstood what they were, a fhrainc. If they're for playing a kind of domino game then they would be called dominoes here in the US also. I've just never heard of anything but the spotted kind (and we have some cultures where they are like a national game, such as among the Cubans in South Florida).
