No description of discoidals would be complete without some description of the game itself. In 1775, James Adair in his 18th Century English wrote a description of the game. The language seems rather difficult to follow in places, but the message seems clear enough:

		The warriors have another favorite game called chungke, which, with propriety of language, may be called ‘running hard labor’. They have near their state-house a square piece of ground well cleaned, and fine sand is carefully strewed over it, when requisite, to promote a swifter motion to what they throw along the surface. Only one or two on a side play at this ancient game. They have a stone about two fingers broad at the edge, and two spans round; each party has a pole of about eight feet long, smooth and tapering at each end, the points flat. They set off abreast of each other at six yards from the end of the play-ground; then one of them hurls the stone on its edge, in as direct a line as he can, a considerable distance toward the middle of the other end of the square; when they have run a few yards, each darts his pole anointed with bear’s oil, with a proper force, as near as he can guess in proportion to the motion of the stone, that the end may lie close to the stone; when this is the case, the person counts two of the game, and, in proportion to the nearness of the poles to the mark, one is counted, unless by measuring both are found to at an equal distance from the stone. In this manner, the players will keep running most part of the day, at half speed, under the violent heat of the sun, staking their silver ornaments, their nose, finger, and ear rings; their breast, arm and wrist-plates; and even all their wearing apparel, except that which barely covers their middle. All the American Indians are much addicted to this game, which it seems to be of early origin, when their forefathers used diversions as simple as their manners. The hurling-stones they use at present were, time immemorial, rubbed smooth on the rocks, and with prodigious labour; they are kept with the strictest religious care, from one generation to another, and are exempted from being buried with the dead. They belong to the town where they are used, and are carefully preserved.

Tennessee Style. Double Cup Variety. D: 5.25" Cape Girardeau Co., MO.	Tennessee Style. Double Cup Variety. D: 5.25" Roane Co., TN.

Discoidals, sometimes called discs, were treasured tribal possessions throughout the Mississippian world. They have been found across all of the great Mississippian lands from eastern Oklahoma, Missouri, Arkansas, Illinois, Indiana, Tennessee, Kentucky, Alabama, Georgia, Louisiana and Mississippi. Although styles often varied from region to region, they were all used as game stones.

Discoidals began appearing at late Woodland Sites in eastern Missouri and southern Illinois around 700 AD. By Mississippian times, chunkey’s popularity spread throughout the Mississippian world. Some Mississippian sites have produced more than one discoidal style, while others have produced only a single style.

Many surviving discoidals are both beautiful and durable. Quartz and granite were often used in the making of these popular game stones. Both materials are extremely hard, and they had to be. Discoidals were continuously used in sporting contests over generations, so they had to be durable. A very few discoidals are made from colorful flint. Discoidals are very popular today with collectors because they come in many styles and colorful materials. Many are so finely made that today they are seen as works of art.

	Tennessee Style. Single Cup Variety. D: 4.8" Rhea Co., TN.

The most frequently encountered Mississippian discoidal styles are the: Tennessee double and single cup, Cahokia, Salt River, Biscuit, Circle Roller, Apple, and Barrel styles.

The Tennessee Style is one of the most desirable discoidal styles. They are usually made of the finest quartz in colors ranging from white, amber, honey, dark red and rich browns. There is at least one Tennessee double cupped discoidal made from colorful flint. Some have diameters in excess of six inches. The double-cupped variety gets its name from the small dimple or cup centered in the discoidal’s larger cup. The Tennessee single cupped style is similar to the double-cupped style in all respects except the small center cup or dimple is omitted. This style is considered a southern style discoidal having its greatest concentration in eastern Tennessee and northern Georgia, but it has been found as far west as southeastern Missouri.

Another extremely popular discoidal style is the Cahokia style which has at least three major varieties. The first variety refers to a discoidal with a cup that nearly reaches the edge of the discoidal. Both cups slope gradually toward the center of the discoidal where it reaches it maximum depth. Some cups are so thin that light can easily pass through the center of the discoidal. The second Cahokia variety has a very thin and sharp edge. The depth of the cup is rather uniform from the edge to the center. The fist two varieties are very narrow compared to their relative diameter. The third variety of Cahokia discoidal is the Mound 72 style named for the discoidals excavated at Cahokia’s Mound 72. This Mound 72 style has a wide cup and relatively thin edge, but it is much thicker than the first two Cahokia styles and tends to have a more rounded circumference. Cahokia discoidals are usually made of colorful quartz, but some are made from granite. Classic Cahokia discoidals usually range from two to four inches in diameter. A few have a perforation in the middle of the cup. Find and distribution patterns show that Cahokia discoidals were primarily used in Illinois and Missouri from the Illinois River to the Missouri bootheel; however, the perforated varieties do appear in western Indiana.

Salt River Style. D: 3" Madison Co., IL.

The Salt River discoidal was one of the most enduring of the discoidal styles. Named after the Salt River in eastern Missouri, it first appeared in eastern Missouri during late Woodland times but continued until Middle Mississippian times (c. 1350). Although occasionally found at the Cahokia complex (Madison and St. Clair Counties in Illinois), it is most often found in parts of northeast Missouri. It is relatively unknown in Mississippian lands outside of this limited area. Its distinctive V-shaped outer rim and relatively narrow cup makes it one of the most unusual styles. The Salt River style ranges in size from two inches to over four inches in diameter. They were most commonly made from colorful granite and dark hard stone, but they were occasionally made from quartz.

Apple Style. D: 3" State of Arkansas.	Apple Style. D: 3.5" Dunklin Co., MO.

The Apple style discoidal is one of the rarest styles. It is so named because of its general apple appearance. Each side has a rather narrow cup in relationship to its diameter. Some cups can be rather deep. Find and distribution patterns suggest that the apple discoidal was a regional style limited to southern Missouri and northern Arkansas. Sizes range from three inches in diameter to over five inches in diameter. Of all the discoidal styles, this one type seems best suited to fit in the chunkey player’s hand as it was rolled at high speed on the chunkey field.

The final three discoidal styles have no cups at all. They are the biscuit style, the circle roller style and the barrel style.

The biscuit style, sometimes called the double convex style or Bradley style, is a rather late Mississippian style. It was introduced around 1350 AD and lasted until protohistoric times. It was favored south and east from the Missouri bootheel, but it did not seem to be popular in Illinois. Apparently the Illinois Mississippians preferred cupped discoidals. Biscuit styles range in size from an inch to over four inches in diameter, and they were usually made from quartz, hard stone or flint. Flint biscuits are very rare and are usually found in Tennessee and northern Alabama.

The Circle Roller style is unique among all discoidals in that it is the only style that is not symmetrical. One side is flat and the other side is domed. Excavations in Georgia suggest that this discoidal style may have been used for an entirely different game than chunkey. Its find and distribution patterns further suggest that it was a northern Georgia style perhaps radiating from the Etowah complex in present-day Cartersville, Georgia. Circle Roller discoidals are made from some of the most attractive stone materials ever used for discoidals. They are encountered in beautiful amber quartz and other translucent materials. The Circle Roller style ranges in size from two to nearly four inches in diameter.

The last discoidal style is the Barrel style. It is perhaps the oddest and most cumbersome of all the discoidal styles. Found primarily in Tennessee, it derives its name from its general barrel style. A rare style, it is the only type that often has a height greater than its diameter. Barrel discoidals are usually very tall, large and heavy. Some barrel discoidals reach a height of over 6 inches and may be nearly five inches in diameter. It is difficult to imagine how a man could roll such a large and awkward discoidal very far. The largest Barrel discoidals may have been ceremonial.
