Let's Ride!: Dreamer is a kids-compatible riding and horse keeping simulation where all the game play elements are embedded into a story line of a young girl trying to convince her father of her being able to raise and take good care of a horse. In order to achieve this, the player has to feed and groom the animal every day, and train it to raise the three statistics the game tracks, making the horse perform better in the equestrian sport disciplines simulated (e.g. dressage and show jumping). Loving horse owners can even embellish the animal's appearance to their own taste.

The player can take his/her horse to rides in various country landscapes or be part of equestrian tournaments that will yield different rewards when successful. Furthermore, one can design his/her own riding courses as well.
