Sequence is an abstract strategy tabletop party game. Sequence was invented by Douglas Reuter and Hamish. They originally called the game Sequence Five. He spent years developing the concept, and, in June 1981, granted Jax Ltd. an exclusive license to manufacture, distribute and sell the board game Sequence and its subsequent variations. The game was first sold in a retail store in 1982.[citation needed] In 2017, Goliath Game Company bought Jax, and in early 2018 also bought all licensor rights and now owns 100% of the game Sequence.[citation needed] Doug Reuter is acknowledged as the inventor of Sequence on all newly produced copies of the game - both on the box and in the printed rules.[1][2]
