Array randômico automático

A interface é preenchida com números entre 1 e 12,
más a impressão é totalmente aleatória, isto sim.
Se a interface é aleatória, os chamados dos números
posicionados na interface também é aleatório.
E segue assim, até que todos os números sejam
chamados, más o programa só finaliza quando 3
sequencias seguindo o mesmo padrão são feitas.

Veja abaixo uma imagem do programa em execução:
