How to Play the Adding Time Game

1. Choose Your Unit Challenge
   At the start menu, you can select which units you want to practice:
   Hours & Minutes: For long durations like movie marathons or flights.
   Minutes & Seconds: For short bursts like race times or songs.
   Mixed Mode: The game will alternate between both.
   

2. Add the Smaller Units First
   Always look at the column on the right (the minutes or seconds).
   Add those two numbers together first.
   The Rule: It takes exactly 60 small units to make 1 large unit.
   

3. Regroup (The “Base-60” Carry)
   If your total in the small column is 60 or more, you must move the “sixties” over to the large column as a single unit.
   Example: If you add 40 min + 30 min, you get 70 min.
   Since 70 is more than 60, you take away 60 to make 1 hour.
   You write 10 in the small box and carry 1 over to the Hours.
   

4. Add the Larger Units
   Add the two numbers in the left column (the hr or min), plus any “1” you carried over from your small unit calculation.
   

Example
Imagine you are in Hours & Minutes mode:
Event 1: 1 hr 45 min
Event 2: 2 hr 25 min
Step 1: Add the minutes
45 + 25 = 70 min.
Step 2: Regroup
Since 70 is more than 60, we subtract 60 to create 1 hr.
We are left with 10 min.
Step 3: Add the hours
1 hr + 2 hr + 1 hr (carry) = 4 hr.
Final Answer: 4 hr 10 min.
