Three age rooms, one arena
Your player card decides which rooms and difficulty levels you can enter — the same way big platforms restrict content by age.
Room 1
Explorers (5-10)
Big friendly boards, hints on, gentle bots and no advanced levels.
Room 2
Challengers (11-14)
Tactics training, timed matches and tougher bots — master level stays locked.
Room 3
Masters (15-21)
Full rules, master-level engines and the global XP leaderboard.
Safety is the feature

- • One-tap reporting on every game screen, reviewed by moderators.
- • No ads and no outside links inside game rooms.
For teachers & schools
SOLO works on any school device with a browser. Track your class through the XP leaderboard, run tournaments by age room, and use the coach levels for chess and checkers clubs.
