Takeaway: Same tiles, three Groups either way.
In Mahjong Island, three 2s, three 3s, and three 4s of one suit can be read two ways.
As three Sets: all the 2s, all the 3s, and all the 4s.
Or as three Runs of 2, 3, and 4 Characters.
Either way it's three Groups, so pick the reading that fits the rest of your hand.
