Each square piece has a number on each side. Position the pieces on the left side of the board so that the same numbers are next to each other. If the numbers don't match, you can't put the piece there. Move quickly: you're being timed!
Karratu bakoitzak zenbaki bat dauka albo bakoitzean. Jarri piezak mahaiko ezker aldean, zenbaki berdinak bata bestearen alboan elkar ukituz. Piezak ezin dira jarri zenbakiak bat ez datozenean. Mugitu bizkor: denbora aurka duzu.
