What are the seven games of the Parelli Natural Horsemanship system and how do they help in training horses?

The Parelli Natural Horsemanship system, developed by Pat Parelli and built on the foundational work of Tom Dorrance, Ray Hunt, and Ronnie Willis, organizes horse-human communication into seven foundational games that together address every aspect of how horses move, think, and relate to pressure. The games are not competitive games but rather interactive exercises that develop the horse's understanding of seven distinct types of communication, each corresponding to a specific pattern of movement or response that all subsequent ridden and ground training builds upon. Understanding each game and its specific contribution to the horse's development clarifies why the system has attracted such a large following and why its structured approach to foundational communication produces horses that are notably easier and safer to develop. The first game is the Friendly Game, which develops the horse's acceptance of being touched, approached, and exposed to novel stimuli without fear or defensive reaction. The premise is simple: the handler approaches, touches, and rubs the horse with the halter rope, the Carrot Stick, plastic bags, and other objects, retreating when the horse tenses and returning when it relaxes, until the horse accepts the contact without alarm. This is a systematic desensitization exercise that directly mirrors the imprinting process and builds the calm acceptance of human contact that all subsequent training depends upon. The second game is the Porcupine Game, which teaches the horse to move away from steady, sustained pressure — a hand, a fingertip, a rope — by yielding toward the pressure's release rather than bracing against it. This is the pressure-and-release concept in its most elemental form, and the horse that understands the Porcupine Game has grasped the foundational communication principle of the entire pressure-and-release training tradition. The game is played by applying pressure at specific points — the poll, the chest, the side, the hindquarters — and waiting with steady, non-escalating pressure until the horse makes any movement away from it, then releasing instantly. The Porcupine Game develops the horse's vocabulary for every rein, leg, and rump rope aid it will ever receive. The third game is the Driving Game, which teaches the horse to move away from rhythmic, intensifying pressure — a swinging rope, a waving hand, a rhythmically applied stimulus — rather than from sustained contact. Where the Porcupine Game teaches response to steady pressure, the Driving Game teaches response to rhythmic pressure, which corresponds to the kind of energy and body language pressure the handler uses at a distance during ground driving, longeing, and liberty work. The Driving Game is particularly important for developing the horse's sensitivity to the handler's position and energy as communication signals rather than requiring constant physical contact for direction. The fourth game is the Yo-Yo Game, which teaches the horse to move backward and forward in a straight line from a rein signal applied at the end of the lead rope, without the handler moving. The horse backs away from rhythmic pressure on the rope and returns toward the handler when the rope goes slack and the handler steps back slightly. This game develops the backup response, the come-forward response, and the straightness that both require, while also developing the horse's attention to the quality of the rope — taut versus slack — as a communication signal. The fifth game is the Circling Game, which is essentially a specific approach to longeing that emphasizes the horse maintaining direction, gait, and pace on the circle for a specific number of laps without continuous driving from the handler. The handler sends the horse out on the circle and then becomes relatively still and neutral, maintaining only enough energy to keep the horse going rather than actively driving every step. The horse that can maintain the circle and gait without continuous handler input has developed the self-direction and forward thinking that reduces the handler's workload and develops the horse's independence and confidence. The sixth game is the Sideways Game, which teaches the horse to move laterally — sideways — from both position pressure and string pressure, developing the lateral flexibility, lateral thinking, and response to lateral aids that all leg yield, sidepass, and lateral work under saddle requires. The horse learns to move its entire body sideways — front and hind ends together — in response to specific pressure patterns, which is among the most gymnastic and most communication-intensive of the seven games. The seventh game is the Squeeze Game, which teaches the horse to move confidently through tight spaces — between the handler and a fence, through a narrow gate, into a trailer — without claustrophobia, bolting, or reluctance. The game is played by progressively narrowing the space the horse is asked to pass through, always moving at a deliberate pace and allowing the horse to understand that tight spaces are navigable rather than trapping. The Squeeze Game directly addresses the trailer loading problem, the narrow gate problem, and any situation where a horse must move through or into a confined space willingly and calmly. Taken together, the seven games address desensitization to touch and stimuli, response to steady pressure, response to rhythmic pressure, backward and forward movement in a straight line, self-maintained circular movement, lateral movement, and confidence in confined spaces — which together constitute a comprehensive foundation for every subsequent training demand. The system's value lies not in the games themselves, which individually mirror exercises found in many training traditions, but in their organized progression and the consistency of the communication principles they establish across all seven categories of movement.
