## What is Plus Monster?

Falling number monsters. Type the answer to the addition problem and your
dragon fires. Solve fast, keep the combo, watch your mental math get sharper.

■ How to play
Number monsters drop from the sky. Answer the addition problem on screen and
your dragon blasts the right one. Chain correct answers to build combos and
power up your shots.

■ Four modes
· Classic — go at your own pace. The best place to get comfortable with addition.
· Time Attack — 15 problems, as fast as you can. 1 to 3 digit mental arithmetic.
· Cosmos — an endless climb. Every floor adds a digit. How high can you go?
· Versus — race a friend through the same problems in real time.

■ Good for
· Kids in early elementary school practising addition and arithmetic
· Adults who want a quick daily brain training and mental math workout
· Parents looking for maths practice that feels like a game, not homework

■ Collect dragons
Solving problems earns star shards. Spend them on eggs and hatch new dragons —
fire, ice, thunder, light and shadow, each with its own projectile.

■ A little every day
Visit streaks and daily missions keep the habit going. Records go on the
leaderboard, and you can send a challenge link to a friend.

Free to play. No in-app purchases.
