Using only four '4's, i.e. 4, 4, 4, and 4, with any number of operators, you must arrive at the chosen solution. For example,

0 = (4+4) – (4+4)
1 = (4 / 4) / (4 / 4)

OK, that's 0 and 1 done, what about the rest? It becomes more difficult with higher numbers!

Zenith is a first-person immersive puzzle game, inspired by The Sentinel by Geoff Crammond. Use the landscape's resources wisely to gain height and depose the Sentinel from the highest point on the landscape. Each landscape takes between 30 seconds and 10 minutes to complete.

Crossmines is a great development of the minesweeper game, where cells can be oddly-shaped and link with other cells. The result is a game of logic that can be enjoyed by easy-going or hardy puzzlers alike!
