On-Call: Deploy Survival

dingcodingco

About this game

It's a rainy night and you're the new on-call engineer at Dingco Pay.

Payments, login, search, photos, the database: five services on an old CRT. When one breaks, an angry customer card appears, and revenue leaks while its hearts drain. Soon the pager rings two at a time, and you only have one pair of hands.

■ Find the cause in the charts
One of three charts looks wrong, and that is the cause: a disk that keeps filling, payments that spike twice, logins that drop to zero. Tap it and you can fix it properly. Curious? Read the raw logs in Browser and the deploy notes in Drive.

■ Type the fix by hand
Tap the command pieces in order. Each right piece chimes a little higher; tap a trap like rm -rf / and your hands freeze for a moment. The last piece deploys the fix.

■ Fast fixes earn tips, back-to-back fixes earn combos
The quicker you fix it properly, the bigger the tip, with x2 and x3 combos for fixes in a row. A quick patch buys time, but it breaks again harder or costs money.

■ A week from Monday to Sunday
Every night adds one new twist: two fires at once, alarms that lie, a sneaky 3 a.m. deploy. Survive a night to pick an upgrade like a coffee machine or deploy automation, and climb from rookie to legendary on-call.

■ New to this? That's fine
Your first incident stops time and shows you one step at a time. Pause whenever you need to think.
