THE FIRST HABIT Pause long enough to read both doors.
The 60-second quick start
Start at Age 0
Follow the tower path until the first pair of doors. The current build starts you in the Baby stage at Age 0.
Read both doors
Do not run through on sight. Check whether each door adds, subtracts, multiplies, or hides its result.
Calculate first
Apply the displayed operation to your current age. A +15 and an x2 can have very different risk later in a run.
Choose control over spectacle
The biggest result is not the objective. Favor the route that keeps your age manageable.
React to Too Old
When the warning appears, your health falls. Take a reduction if one appears, or keep moving toward the finish.
Cross the finish
A finish is separate from the Age 67 side objective. After a clear, the trophy count rises and you can run again.
A simple door rule for your first run
LOWER RISK
Small additions or reductions
They preserve room for later stages and make your next calculation easier.
HIGHER RISK
Late multipliers or mystery doors
Their cost grows with your age. Use them only when the visible alternative is worse.
