Hoverdia's First-of-its-kind Two-in-one 8x8 boxes as well as 9x9 boxes logic-number puzzles are partially filled up with some pre-set numbers.

The aim is to fill up each block with a set of designated numbers exclusively.

No repeating number on each horizontal and vertical block.

The entire puzzle is alternatively represented either by 4 quadrants of 4x4 boxes or by 9 regions of 3x3 boxes.

Each block, either with 4 boxes in each quadrant or with 3 boxes in each region, must be horizontally and vertically added up to a designated total sum accordingly.

These styles of puzzles are very easy and fun as there are full of alternatives in decoding it, and moreover it is not a rigid puzzle game which would be usually aborted halfway through.

Always start with RULE TWO as it is one of the two rules, which is indirectly known as alternative, for decoding these styles of puzzles in each quadrant (4x4 boxes) or each region (3x3 boxes).

Each quadrant (4x4 boxes) or each region (3x3 boxes) can be easily cleared off by applying RULE TWO respectively even with only two or three known numbers.

"There's always an opportunity, if there is an alternative"
