Double Up

Double Up is a daily number puzzle where your mission is to strategically drop numbered blocks into a 4x3 grid, merging matching numbers to build the highest score possible.

Each turn, you place a block into one of four columns. It falls to the lowest empty space, just like dropping a piece in Connect Four. When two blocks with the same number land in adjacent cells (horizontally, vertically, or diagonally), they merge into a single block worth double the value. Chain merges together to rack up points.

• Place blocks by tapping a column or pressing A, S, D, or F on desktop.
• Blocks fall to the lowest empty space in that column.
• Match two identical numbers in adjacent cells to merge them and double their value.
• Keep merging to build higher numbers and maximize your score.
• The puzzle ends when the grid fills up.
• A new challenge drops every day with a fresh set of blocks.

Why we like it:

• ✅Every move matters in a tiny grid, so there's real strategy despite the compact size.
• ✅The merge mechanic is instantly satisfying when you chain combos together.
• ✅Quick enough to play on a coffee break but deep enough to keep you thinking.

Hint: Try to keep your highest value blocks together in the same area. Building vertical or horizontal lines of similar numbers sets up future merge opportunities better than scattering values across the grid.
