|By clue 5, Rich accepted the dare first, followed immediately by Cassidy and then
by the teen who got a tattoo on his chest; since none of the three got the shark
or football tattoos, the boys who did are the fourth and fifth to the other three.
By clue 1, one of the boys who got the shark and football tattoos must have gotten
it on his shoulder; while by clue 2, the other of the boys who got the shark and
football tattoos got it on the ankle. Rich and Cassidy then got their tattoos on
the biceps and forearm or vice versa. Since Michael didn't get tattooed on the
shoulder (1) or ankle (8) and isn't Cassidy (8), Michael got a tattoo on his chest.
Since Rich isn't Devlin (3), by clue 9, Billy must be one of the boys who got the
shark and football tattoos. Since Gabe didn't get tattooed on the biceps or forearm
(4), he also can't be Cassidy. John is Cassidy. Neither Rich (3), Gabe (6), nor
Billy (9) is Devlin, so Michael is. By clue 7, the boy who got his biceps tattooed
didn't get his girlfriend's initials or the ace of spades done; he got the dragon.
He isn't John (10) and is thus Rich. By elimination, John got a tattoo on his
forearm. Michael Devlin got the ace of spades and John Cassidy the initials (14).
By clue 11, Rich is Fair. Malone got the shark and Hammond the football tattoo (13).
By clue 6, Gabe is Hammond and Billy Malone. Gabe Hammond got the football on his ankle
and Billy Malone the shark on his shoulder (12). The five friends got their first
tattoos as follows:
- Rich Fair, dragon on the biceps
- John Cassidy, girlfriend's initials on the forearm
- Michael Devlin, ace of spades on the chest
- Billy Malone, shark on the shoulder
- Gabe Hammond, football on the ankle
