Sonic X is an educational game released for the Leapster handheld learning game system. It is based on the Sonic X anime and is aimed towards children between the ages five to seven. Progress is made primarily through solving mathematical problems such as numerical ordering, addition and subtraction.
The story of Sonic X starts in Station Square, with Christopher Thorndyke introducing himself as Sonic's friend. Then, Dr. Eggman comes in, jealous of Sonic's name being everywhere. Thus, he kidnaps Amy, Tails and Knuckles. When Sonic hears his friends calling for his help, he arrives on the scene, and Eggman tells him that he will have to pass through his new math robots to save his allies.
Sonic traverses through various locations, saving his friends in the process while overcoming Eggman's math robots. After all levels are completed, Eggman's plans are foiled, and Sonic goes to Station Square, where he is cheered on by many people, including Chris.
Sonic X is an educational, 2D side-scroller platformer video game, with a similar gameplay to that from early Sonic games. Here, the player takes control of Sonic, whose basic abilities are running and jumping. Sonic X is split into three zones, each divided into three levels.
The main objective of Sonic X is to get to the end of each of the levels, which are designed to be split into several rooms with mathematical problems, which require the player to find the right numbers in the right order; doing so will allow them to progress. Throughout the levels, Goal Plates are sometimes seen, although they do not change anything. To finish the first two levels, the player has to touch the local Star Post in each of them. In the third Zones on the other hand, a Goal Plate with the face of one of Sonic's friends has to be spun.
Golden rings appear scattered throughout the game, with ninety-nine of them appearing in each Zone. Finishing a Zone with every golden ring collected will grant the player one of the seven Chaos emeralds. When all seven Chaos emeralds are collected, collecting all golden rings will power up the Master emerald instead. However, collecting all seven Chaos emeralds and fully powering up the Master emerald will not grant any reward.
In addition to the main zones, Sonic X features three mini-games, which can be acceded either through their respective zones or through a boat symbol in the map. The mini-games are:
- Eggman's Super Sucky Machine: Found in Station Square. The player must choose the right numbers in the right order in order to progress.
- Math Robot Round-Up: Found in Angel Island. The player must use the Leapster pencil to round up enough math robots in order to progress.
- Aerial Automations: Found in Eggman's Base. The player must tap enough math robots in order to progress.

Sonic X has three zones divided into three levels each. In each level, the player must solve simple mathematical problems. The zones are:
- Station Square: Teaches the player number identification, number/object association and skip counting by 2s, 5s and 10s.
- Angel Island: Teaches the player simple and intermediate addition, with and without visual support.
- Eggman's Base: Teaches the player simple and intermediate substraction, with and without visual support.
- This is the only Sonic game to feature Christopher Thorndyke (apart from a cameo appearance in Sonic Adventure DX: Director's Cut). He appears in the game's animated cutscenes and cheers Sonic on when clearing a math problem.
- This marks the first time a Sonic game has cutscenes to be animated in Adobe Flash.
- Most sprites are taken from earlier Sonic games, such as Sonic the Hedgehog 3 & Knuckles and Sonic Advance.
