# Odd Squad: Blob Chase Offers Fun Problem Solving Involving Addition and Subtraction

Odd Squad: Blob Chase offers fun problem solving involving addition and subtraction.

I am a math geek, and I adore beautiful math games, such as Twelve a Dozen. Both my sons also share my interest, so we were all excited when we found a great new math game called Odd Squad: Blob Chase.

### 60 Levels of Problem Solving Involving Addition and Subtraction

This game is adapted from a brand new PBS Kids series called Odd Squad. Using gadgets like addition operator and subtraction operator, you are expected to gather all the blobs trying to escape from the Odd Squad headquarter.

The blobs will run around whenever there is an open passage. Different blobs move differently; for example, the blue blobs are afraid of falling off platforms so to move them you need elevating tubes. On the other hand, the purple and pink ones are not afraid of falling off, so you need to plan their passageways carefully.

The game is all about controlling the length of the passageways and the elevating tubes. You can use the +1, +2, +3, +4 operators to extend their lengths, or -1, -2, -3, -4 operators to reduce their lengths. Sometimes, you may also need to use the negative operators to clear up roadblocks.

As you unlock new levels and new operators, you may find a doubling operator, a halving operator, and even a -10 operator. The goal is to use them in any combination to guide as many blobs as possible to the collector machine.

### Parents Need to Know

Odd Squad: Blob Chase is only available for the iPad. The game’s difficulty level is suitable for kids ages five and up. It covers early math operations, such as addition, subtraction, doubling, and halving. The game works great in Airplane mode, and has no in-app purchase, no ads, and no links to social networks.

The early levels in this game are relatively simple; my three-year-old can complete the addition levels on his own. But, things start to be more complex once you have unlocked all the operators. Many of the later levels require planning, backtracking, and sometimes fast thinking.

If you are stuck on a level, you can always tap on the Hint button on the top right corner of the screen. The game will provide you with an audio guide for solving the current level.

Count how long each passageway should be before you extend them. You may not have the chance to offset your mistakes.

### Playing Tips

After watching my five-year-old complete the entire game, here are several pointers that may be helpful for first timers:

• If you want a blob to move in an opposite direction, simply tap the blob.
• Be careful of the pink blobs. They move really fast, so you need to close the platform to prevent them from falling off. Think quickly. You can also tap the pink blobs to go back and get a few extra seconds to plan.
• Work your way from the collector machine to the blobs, and not the other way around. Most of the levels require you to clear blocks or extend the passageways in a correct sequence.
• Before using any of the operators, estimate the length of the passageways or elevating tubes you need. This is essential because you may not have the negating operators to offset any mistakes.
• When trying to move the purple or pink blobs through the elevating tubes, you may need to extend the tubes in “safe” steps. Otherwise, they will fall off a tube exit and off the screen.
In this final level, you need to use all the tricks you learned in the previous levels.

### Conclusion

Odd Squad: Blob Chase is a fun math game for kids ages 5+ to practice their early arithmetic skills. It offers 60 levels of challenging problem solving involving addition, subtraction, doubling and halving. If your kids enjoy puzzle platformer games such as Twelve a Dozen, they’re going to love Odd Squad: Blob Chase.
