When any clusters have been deleted, if there is only a single color block in the field, SINGLE COLOR BONUS will be obtained.
After this, if you can create another cluster on right side of timeline using next block ( e.g. single color cluster), SINGLE COLOR BONUS will be obtained again after it has been deleted.
This technique helps saving time in Challenge mode.

When it is erased like this at the initial stage, only one block is in state.




















Prepare some of this.

By using this, it is possible to reach Lv 100 without difficulty by processing the checker block and the L+1 character block each time.

In above section I talked about "odd number of field blocks".
Now you may think about "how can I make that?".
That is simple. "Deleting odd number of blocks leaves odd number of blocks."

For example, there is a 3x3 cluster in situation of this screenshot. At next timeline period, 9 blocks will be deleted and will left 7 blocks on field.

After while the field became like this.

Let's give specific examples by saying










The state of the above screenshot is recognized as having Three 2 × 2 squares.
But the blocks are in an overlapping state with each other, so they disappear odd numbers.
As a result, an odd number of blocks remain.

And this state I advanced the game for a while.










It is somewhat hard to see by overlapping with the timeline, but it is possible to process it by making an L+1-shaped, Checkered pattern-color block into a square.

Again, if you place some "odd number of blocks" in the field
You can process any block without stacking it.
The result is a shortcut to clear.
If you aim for a high score you need another strategy, but let's explain it on another occasion.
