Tip Drill

Restaurant math at speed. Ten rounds. Fifteen seconds each.

Why Tip Drill is in Kefiw Daily

What it trains

Tip Drill trains quick restaurant math: estimating common tip rates, checking totals, and separating the service percentage from the bill.

How scoring works

Correct answers score higher when they are quick. The goal is a repeatable mental shortcut for 15, 18, and 20 percent without overthinking.

How to use it

Use it as a small everyday-money drill for meals, service quotes, shared bills, and situations where a quick estimate prevents decision friction.

Privacy and review

Round state stays in local browser storage unless you choose to post a score. Use Tip Calculator after the round to review the underlying tool or practice family.

How to make the practice useful

Treat the score as a signal, not a judgment. A low score usually means the round exposed a specific skill gap: estimating too quickly, missing a constraint, losing track of a prior clue, or choosing the first plausible answer. After the timer ends, look back at one missed item and name the decision rule you would use next time. That short review is what turns a daily game into a cognitive-boost routine.
