Tip Jar

Work out the tip, add coins to reach exactly that amount, then press Done. Eight rounds.

How to play Tip Jar

Each round shows a restaurant bill and a tip percentage, such as 20% on $60.00. Work out the tip, then press the coin buttons ($5, $1, 25¢, 10¢, 5¢) to fill the jar with exactly that amount and press Done. The jar fills as you add coins and turns red if you go over.

The math behind it

Tip = bill × percent ÷ 100. A 20% tip on $60 is $12. A quick way to find 15% is to find 10% (move the decimal) and add half of it: on $60, 10% is $6, half is $3, so 15% is $9. For 20%, double the 10% figure. For 25%, take a quarter of the bill.

Tipping in the US

In the US a tip of 15% to 20% is normal for table service, and many people use 18% to 25% now. Check the receipt first, because some restaurants add a service charge to large groups. The tip calculator splits a bill between people and rounds the total for you.
