Good enough as a multiplayer runner, matches are quick and it's basically the equivalent of Mario Kart Tour for Sonic games. I like the character designs here a lot and basically every major Sonic character is playable, including some unique redesigns.

Unfortunately, Speed Battle falls into the same trap as Clash Royale or similar games, gating character unlocks and even their respective upgrades behind lootboxes, which take several real-life hours to open up. Even then, you don't just get characters like that, they're locked behind a card system, so you could get like 20 out of 90 cards for Knuckles out of a chest, and it'd still take you some time to get him. Or you could pay, and buy something like this advertised 4X VALUE pack in the shop to get 1000 cards for Chaos instantly and you even get 75k coins on top - if that isn't a good deal, then what is. All for the low price of 60€. Not to mention that those deals are so good, the game has to constantly remind you of them through pop-ups whenever you just browse through the main menu. Also, you're forced to watch ads after every match. Awesome.
