Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !

The pipi is a shellfish with a solid white, elongated shell with the apex at the middle. It is covered by a thin yellow periostracum. It is abundant in sandy and silty mud in estuaries, and harbours where there is considerable water flow. The daily limit is 150 per person, and although a minimum size is not stipulated in the regulations, only larger pipi should be taken. For Māori, pipi are a traditional resource. In earlier times Māori made specific flax baskets to gather them. Smaller specimens would fall between the woven strips and back into the beds as the basket was gently swirled through the water.
Maximum length is 83 mm, and height 51 mm.
