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 vervet monkey (Chlorocebus pygerythrus), or simply vervet, is an Old World monkey of the family Cercopithecidae native to Africa. The term "vervet" is also used to refer to all the members of the genus Chlorocebus.
There are five distinct subspecies of vervet monkey:
The vervet monkey has a black face with a white fringe of hair, while the overall body colour is mostly grizzled-grey. The males of all species have a pale blue scrotum and a red penis. The species exhibits sexual dimorphism, the males are larger in weight and body length. Adult males weigh between 3.9 and 8.0 kilograms (8.6 and 18 lb), averaging 5.5 kilograms (12 lb), and have a body length between 420 and 600 millimetres (17 and 24 in), averaging 490 millimetres (19 in) from the top of the head to the base of the tail. Adult females weigh between 3.4 and 5.3 kilograms (7.5 and 12 lb) and average 4.1 kilograms (9.0 lb), and measure between 300 and 495 millimetres (12 and 19.5 in), averaging 426 millimetres (16.8 in).
The vervet monkey uses different calls upon detecting different types of predators, including leopards, snakes and eagles. Infants appear to have an innate tendency to make these alarm calls, and adult monkeys seem to give positive reinforcement when their young make the right call, by repeating the alarm. Mothers have been reported to punish young giving the wrong call.
The vervet monkey eats a wide range of fruits, figs, leaves, seeds and flowers. It also eats birds' eggs and young chicks, and insects (grasshoppers and termites). In human inhabited environments it will eat bread and various crops; especially maize.
The vervet monkey ranges throughout much of Southern and East Africa, being found from Ethiopia, Somalia and extreme southern Sudan, to South Africa. It is not found west of the East African Rift or the Luangwa River, where it is replaced by the closely related malbrouck (C. cynosuros). The vervet monkey inhabits savanna, riverine woodland, coastal forest and mountains up to 4000 m (13,100 ft). They are adaptable and able to persist in secondary and/or highly fragmented vegetation, including cultivated areas, and sometimes are found living in both rural and urban environments.
Introduced vervets also occur in Barbados, Saint Kitts, and Nevis. Dania Beach, Florida is also home to about 20 vervets. 
In spite of low predator populations in many areas where human development has encroached on wild territories, this species is killed by electricity pylons, vehicles, dogs, pellet guns, poison, and bullets and is trapped for traditional medicine, bush meat, and for biomedical research. The vervet monkey has a complex and fragile social system, its persecution is thought to have affected troop structures and diminishing numbers.
Multiple organisations are involved in vervet monkey conservation.
This species was known in ancient Egypt including the Red Sea Mountains and the Nile Valley. From fresco artworks found in Akrotiri on the Mediterranean island of Santorini there is evidence that the vervet monkey was known to the inhabitants of this settlement around 2000 BC; this fact is most noted for evidence of early contact between Egypt and Akrotiri.
