differ generally. The first was Triple Yahtzee, developed in 1972. The game has inspired two short-lived television game shows: 1975's Spin-Off on CBS and 1988's syndicated Yahtzee. Online versions There are a large number of versions of Yahtzee which can be played online or are available to download. "Open Yahtzee" is a cross-platform open-source (free) version of Yahtzee for one player. "YachtC" is a commercially available free app on the Google Play Store. It has 3 variations: The traditional version, a "7-sided" dice version called "Lucky7", and a "TriColor" version similar to Kismet "Gidd.io" is a free multiplayer platform where Yahtzee can be played online with up to 20 players. Similar games There are a large number of related games. Yatzy is one of the most popular. Yatzy rules and scoring categories are somewhat different from Yahtzee: The bonus for reaching 63 or more points in the Upper Section is normally 50 points. There are two extra boxes for the "One Pair" and "Two Pair" categories. These score the total of the pair(s) involved. For instance, 5-5-4-4-1 will score 10 points in the One Pair box and 18 in the Two Pair box. In the Two Pair category, the pairs must be different. The Three-of-a-Kind and Four-of-a-Kind categories are scored using the total of the needed number of same-faced dice. For instance, 5-5-5-5-6 will score 20 points in Four-of-a-Kind and 15 points in Three-of-a-Kind. This scoring rule is the same as the Four-of-a-Kind scoring used in Yacht. Full House scores the total of all dice, as in Yacht. Small Straight and Large Straight have the same definitions as in Yacht. A Small Straight is 1-2-3-4-5 and scores 15 points (the total of the dice faces); the Large Straight is 2-3-4-5-6 and scores 20 points (again the combined value of the dice). There are no Yahtzee bonuses or Joker rule. Yahtzees can be scored in other categories under the normal scoring rules. For example, a Yahtzee of sixes will score 12 in the One Pair box, 18 in Three-of-a-Kind, 24 in Four-of-a-Kind, 30 in Sixes or Chance and 0 in Two Pair, Full House, Small Straight and Large Straight boxes.
