Daley Thompson's Decathlon is an athletics simulation in a similar vein to 1983's Track & Field arcade game by Konami and Decathlon by David Crane (a.k.a. The Activision Decathlon). It was created to capitalise on the success of those games, which in turn had been created to capitalise on the popularity of athletics at the time (sparked by the 1981 movie Chariots of Fire, and the highly publicised 1984 Olympic Games).

The game is controlled with three keys (or joystick actions): left foot, right foot, and action (jump or throw depending on the event). As with the games mentioned above, the input method involves alternately hitting the left foot and right foot keys as quickly as possible, the quicker a consecutive sequence of left and right presses is entered, the faster the player runs. Games with this control method were often refered to as 'joystick wagglers'. (The system has remained a favourite with developers throughout the ages, cropping up in titles as varied as Viz: The Computer Game, Sydney 2000 and the Mario Party games.)

All ten of the decathlon events are represented in the game: 100 Metres, Long Jump, Shot Putt, High Jump, 400 Metres, 110m Hurdles, Pole Vault, Discus, Javelin and 1500 Metres. Because there was not enough memory to store the all the events at once, the game is a 'multiloader': the player(s) play through the first five events (day one) and then are prompted to start the tape to load in the remaining five events (day two). For each event you must achieve a minimum qualifying distance or time (getting three attempts in the non-running events), and failure to qualify costs you one of three lives. A successful performance in a given event makes your athlete raise his arms in delight, and elicits a cheering (ZX Spectrum version: hissing) response from the crowd. A failure makes your athlete scratch his head in frustrated disgust.

The 100m and 400m are the most basic events. You simply have to bash away at the left and right keys to keep your speed as high as possible as your smoothly-animated little athlete guy runs from left to right on a scrolling track with crowds passing by in parallax in the background. The 110m hurdles adds, well, hurdles, which have to be cleared by tapping the action button at the correct moment, while still waggling furiously. The 1500 metres thankfully does not involve five or six minutes of sustained button bashing- instead you simply have to press one button to accelerate and one to slow down. An element of strategy is introduced by the inclusion of an energy (stamina) bar, which is depleted more rapidly the faster you run, and is slowly replenished if you run a lot slower than full tilt. If all your stamina is depleted you are forced to retire from the race.

Long Jump and High Jump are presented from the same side-on view as the running events, and in both cases centre on the timing of your jump (jump too late or early and score a foul), with the speed that you run at the point of launch determining how high or far you go. Pole Vault is treated similarly, although the angle at which the pole hits the ground has an effect on whether you can successfully clear the bar. (This event is particularly infuriating as you ideally need to start lowering the pole before the crossbars come onto the screen.)

For the throwing events, the shot-putt and javelin are both treated very similarly, with the running speed being the major factor in how far they go. The angle of the javelin can be controlled by the duration that the action button is held down for, although this is usually only a split second making fine-tuning difficult if not impossible. The discus event is handled quite differently however- the pit/cage/launching area is depicted from a bird's eye view, with the athlete, arms akimbo, being spun around with the left and right keys. The throw button must be pressed at the exact right moment or the discus will be launched fruitlessly into a wall. Managing to throw the discus the right way cuts to a zoomed-out view of the field, showing the discus travelling through the air and hitting the ground. (Humourously, a foul shot still makes your athlete do his 'head scratching' routine from the side-on events, making him appear to fall over in the pit.)

It has frequently been pointed out that in the ZX Spectrum version, the player controlled athlete is white where as Daley Thompson is in fact, black. (This is meant, at least I hope so, as a joke- the sprite you control isn't just white-skinned, he's completely white due to the limited way in which the Spectrum handles colours.) Logically, the player character is not supposed to be Daley Thompson himself. He doesn't even have a moustache.

The game was a significant commercial success for Ocean (as a result being included on the They Sold A Million compilation). The game spawned two semi-sequels, Daley Thompson's Supertest in 1985, and Daley Thompson's Olympic Challenge in 1988 (which was also released on the 16-bit formats).
