Hnefatafl 30X30 boat board
Hnefatafl (King's Table) is a strategic board game. It was conceived by the Vikings and was popular before chess came up, about around 1100. The game has simpler rules than chess, but is strategically at least as difficult. Theorized game is a non-symmetrical game (majority/minority game).
Hnefatafl belongs to the Tafl family. These are games for two players, in which one side is numerically weaker than the other, but because of the strategic objective is not necessarily at a disadvantage. In some cases, the play value or strength of a piece of the numerically weak party is greater than that of the larger counterparty.
The games of the Romans such as ludus latrunculorum went from equal parties and the battle out. In the world of experience of the Germans, the uneven struggle and the robbery of a king and his bodyguard was recognisable. Hnefatafl seems to be based on the Roman game.  In England, the board game is only demonstrable as part of the Latinization in the first century of our era.
The goal of the Tafl games is that the weaker pieces try to beat the smaller number of stronger pieces. The opposing party is trying to prevent that.
The game Tafl is called in the Edda, the Icelandic sagas. The oldest recovered board is a fragment of an 18 x 18-pitch game board (Denmark, dated about 400 AD). The Vikings have spread the game. It has been found in Greenland, Iceland, Ireland, Wales and Ukraine. Until the eleventh century it was popular, after which the Tafl was quickly supplanted by Chess. The last source references are from 1587 (Tawlbwrrd, Wales) and 1732 (Tablut, Lapland).
