Question: What game  is the sixth (and final) release in the "GIPF" project of six abstract strategy games, Niagara or PÜNCT?

full_context: Document 1: TAMSK: TAMSK is the second board game in the "GIPF" Project of six abstract strategy games, and was published in 1998. Players move sand hourglass timers and drop plastic rings around spaces on a hexagonal board in an attempt to limit their opponent's moves. Each player starts the game with 32 rings, and the player with the fewest remaining rings at the end of the game is the winner. The game is unique among the "GIPF" Project games in having time as a central game component, and the manner in which time is used is possibly unique among board games in general.

It has 104 cards, each bearing a number and one to seven bull's heads symbols that represent penalty points. A round of ten turns is played where all players place one card of their choice onto the table. The placed cards are arranged on four rows according to fixed rules. If placed onto a row that already has 5 cards then the player receives those five cards, which count as penalty points that are totted up at the end of the round. Rounds are played until a player reaches 66 points, whereupon the player with the least penalty points wins. The game's suggested minimum age is 10 years, and lasts on average about 45 minutes.
