Numerift is a strategic number puzzle inspired by the familiar 9×9 structure of Sudoku and the satisfying placement mechanics of block puzzle games.

Place numbers on the board, merge matching values, and complete rows, columns, or 3×3 boxes to clear space. Every placement affects your next move, so careful planning is the key to building combos and achieving a higher score.

There is no timer. Take your time, study the board, and find the best place for every number.

HOW TO PLAY

• Drag numbers onto empty cells of the 9×9 grid.
• Place matching numbers together to merge them into a higher value.
• Fill a complete row, column, or 3×3 box to clear it.
• Create consecutive merges and clears to build combos.
• Keep enough space available for future number batches.
• Continue playing until there are no valid moves remaining.

SUDOKU-INSPIRED BOARD

Numerift uses the recognizable structure of a Sudoku board, divided into rows, columns, and 3×3 boxes.

Unlike traditional Sudoku, you are not solving a prepared number grid. You decide where each generated number should be placed while managing merges, completed areas, and the remaining board space.

MERGE AND BUILD

Matching numbers can combine into larger values. Use merging to free cells, prepare future clears, and create better scoring opportunities.

A useful move may solve an immediate problem. A great move also prepares the board for what comes next.

CLEAR THE GRID

Complete any of the following areas to clear its numbers:

• A horizontal row
• A vertical column
• A 3×3 box

Plan placements that contribute to several areas at once. Completing multiple areas together can produce stronger clears and higher scores.

USEFUL TOOLS

• Eraser — Remove a number that blocks your strategy.
• Reroll — Replace the current number batch, but prepare for threats to advance.
• Reserve — Save a number and place it later when the timing is better.

EASY TO LEARN, HARD TO MASTER

Numerift combines familiar puzzle ideas into a different kind of number challenge.

The controls are simple, but maintaining the board requires planning. Decide whether to merge immediately, prepare a completed area, save a number for later, or protect space for the next batch.

Place numbers carefully. Merge matching values. Complete the grid areas. Keep your run alive and challenge your highest score.

PLACE. MERGE. CLEAR.
