Cubisum

Cubisum is a daily number puzzle game where your mission is to match all the numbers on a grid of boxes by clicking them in the right sequence to increment their neighbors.

You start with a grid where each box shows a target number. Click or tap a box to increase the values of all adjacent boxes by one. Right click or long press to decrease them. Each box can be clicked up to four times before it resets, indicated by dots or color changes. Your goal is to manipulate the grid until every box displays the same matching number.

• Click a box to increment all neighboring boxes by one.
• Right click or long press to decrement instead.
• Each box can be clicked up to 4 times before resetting.
• Color or dots show how many times a box has been clicked.
• Solve the puzzle in as few moves as possible.
• A new puzzle drops daily at 5 PM your local time.

Why we like it:

• ✅The ripple effect mechanic turns every move into a small logic puzzle.
• ✅Multiplayer mode adds competitive urgency to an already tight challenge.
• ✅Tracking your move count gives you a reason to replay and optimize.

Hint: Work backwards from the target. Identify which boxes need the most changes, then figure out which clicks will cascade the right values without overshooting.
