Activities
In Baldi’s Basics Plus, most notebooks are guarded by an activity: a short classroom puzzle you have to solve before the notebook is yours. There are three of them, Math Machine, Balloon Buster and Match Machine. Solve one and you get stamina and a notebook; fail and Baldi gets faster and comes straight to you. This guide explains how each activity works and how to solve it without mistakes.
The basics
Every activity classroom has a chalkboard that explains how to solve its activity, and since version 0.14 classrooms also have a sign outside showing which activity is inside. Read the board before you start: it takes a few seconds, and a failed attempt costs far more.
| Outcome | What happens |
|---|---|
| Success | You earn the notebook and a stamina boost. Baldi pauses to praise you, and bumping into him during the praise doesn’t cost a life |
| Failure | Baldi gets faster and hears where you are |
| Locked room | If the classroom’s doors are locked, solving its activity unlocks them |
Math Machine
The Math Machine shows a math problem. The possible answers are on the number balloons floating around the room: pick the balloon with the right number and submit it at the machine. It lights up to show whether the answer was right, and a correct answer plays its own sound.
- Read the whole problem before you touch a balloon.
- Double-check the operation: a misread sign is an easy way to fail.
- Math Machines sit close to walls, so you can’t hide behind them.
Balloon Buster
Added in version 0.12. The device shows a number, and the room is full of balloons. Pop balloons until only that number is left, then pull the pulley to submit. The remaining balloons are popped and counted, and if the count matches, the activity is complete.
| You fail if… | How to avoid it |
|---|---|
| Too many balloons are left when you submit | Count twice before you pull the pulley |
| You pop too many | Slow down near the target number and pop one at a time |
The device has a hologram that turns off when the room has no power and turns red when you fail.
Match Machine
Also added in version 0.12. All balloons start as question marks, and clicking one reveals an object. Reveal two that match and they stay revealed: you get stamina and YTPs, and Baldi stops to praise you. Reveal two that don’t match and they turn back into exclamation-mark balloons after a moment.
- Three matches win. Since version 0.14 you only need three matches. The last pair reveals itself automatically.
- Remember what you saw. You fail if you reveal a mismatched pair when at least one of the two balloons was already an exclamation mark, that is, one you had seen before.
In the Match Machine, a balloon you have already seen is a trap if you pick it with the wrong partner. Only click a seen balloon when you know where its match is.
Bonus questions
When a bonus question is available, a hanging neon BONUS sign appears under the classroom’s activity sign. Answering it gives extra YTPs. Bonus questions can’t be answered in rooms without power, which matters on Maintenance levels. In Endless mode, an activity’s bonus question only becomes available after you collect that activity’s notebook.
Activities and the rest of the level
- Power. On Maintenance levels, a classroom must have power before its activity can be solved. Find its lever first; our Maintenance guide explains how.
- Chalkles. Since version 0.12, making progress on an activity lowers his charge, and completing it resets him fully.
- Baldi. Every notebook makes him a little faster, and the last one brings him to full speed for the level.
A clean approach
- Check the sign outside. Know which activity is inside before you open the door.
- Read the chalkboard. It explains the activity in the room.
- Look around first. Count balloons or note positions before acting.
- Act slowly. A careful solve takes seconds. A failed one makes the rest of the level harder.
- Use the praise. Baldi pauses after a success. Use the moment to leave the room.
Save an activity for the end of your route if you can. Completing it right before the last notebook gives you a stamina boost just when you need to run for the elevators.
FAQ
What happens if I fail an activity?
Baldi gets faster and hears where you are. Leave the room quickly, or be ready with an item.
Why can’t I solve this activity?
On Maintenance levels, the room may have no power. Raise the lever that its cable leads to.
How many matches does the Match Machine need?
Three. Since version 0.14, the last pair reveals itself once you have made three matches.
