Calc Bingo

This is a game combined bingo and calculation training.
Tap falling number icons to select proper one then establish the bingos.

The game starts and, after a moment, several number icons will appear and start falling.
If tap a falling number icon, the icon will go upward.
Prevent or choose the number icon to get the result which matches an element of the bingo card.
The calculation will be executed when those number icons fill the formula area indicating several operators.
If the result matches the element of the bingo card, the element will be marked (the background color is changed).
Establish the bingos vertically, laterally or obliquely.
A number of bingos can be established at the same time as well and a special point can be obtained.
If the all targets displayed on top of the scene are collected, you will beat the level.
If the bingo card reaches the formula area, the game is over.

If you tap the continue button on the opening scene, you can restart the highest level that you have played before.
