Meaning

noun a small cube with 1 to 6 spots on the six faces; used in gambling to generate random numbers

verb cut into cubes

verb play dice

originFrom Middle English dys, plural of dy. See the etymology of die (etymology 2) for further information. The voiceless /s/ was most likely retained because the word felt like a collective term rather than a plural form (compare pence), and the spelling dice is a result of the pronunciation.
