Description (written by the developer; not a statement by this register)
Warning: Currently, sphere stress tests are broken, and we don't recommend testing with them. ⚠ GUIs on phones or tablets may be incorrectly scaled ⚠ Welcome to Part Lag Test 2026 (originally 2025)! Once you join the game, you can select which shape you want to lag test with, (part, sphere, or cylinder) and then the stress test will begin. The game will spawn blocks indefinitely until your game crashes. Even if an active server has been ongoing, do not worry. All the code in our game is client-sided so once you rejoin or join an already big server, your counter gets reset and everything restarts.

Growth
Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.

Badge funnel
How many players have ever earned each badge — a proxy for how far players get before they stop. Steep drop-offs mark where a game loses people. Win rate is the past-day share of players who earned it; categories are assigned by a language model from each badge’s own name and description.
