Soon, 10s and 20s Jump Out at You.

DIGITRE:SUM 10/20 is a fast math action puzzle where you link adjacent numbers to total 10 or 20 and clear them from the board.

At first, even spotting a combination that totals 10 can be difficult. But with every attempt, combinations begin to emerge from what once looked like scattered numbers. Soon, 10s and 20s jump out at you—and careful calculation gives way to instinctive action.

Play again and again to chase SCORE and cut CLEAR TIME. Simple rules, the thrill of chasing records, and the spirit of classic arcade puzzle games—all through numbers.

ARCADE

Clear numbers one after another on a board that rises from below. Advance through the LEVELs and aim for ALL CLEAR before the blocks reach the top.

A higher SCORE, a shorter CLEAR TIME, a better rank. Keep playing and beat your own records.

Build CHAINs with consecutive clears to boost your score. Keep clearing glowing TARGET blocks to grow your TARGET STREAK for even more points. When enabled, BURST clears blocks across the board to help you escape a tight spot.

VS

Clear TARGETs to send attacks that push up your opponent’s board. Build CHAINs and TARGET STREAKs for bigger attacks and force your opponent toward the top.

Your own attacks can cancel incoming attacks while they are pending. Once an attack activates, it can no longer be cancelled, so timing matters. If you cannot lower your board within three seconds at the top, you lose. Choose when to attack and when to defend to win.

• VS HUMAN — Two-player matches on the same PC. Trade attacks with a friend and compete for victory.
  
• VS CPU — Choose a CPU difficulty level that matches your skill.

PUZZLE

Make 10 or 20 on a fixed board with no rising blocks, and remove every number to solve the puzzle. Think ahead about how the remaining blocks will fall and set up your next move.

• STAGE — Take your time with fixed puzzles and no time limit. Clear every block, then try to find an optimal solution with fewer moves.
  
• RUSH — Take on a course of 50 or 100 randomly selected puzzles. Each puzzle has a two-minute limit; three passes or timeouts in total end the run. Solve as many as you can, then finish the course to chase a new best total time.

CHALLENGE

Two challenges test your speed and endurance on a rising board. Choose between cutting your time and pushing your score higher.

• BLITZ — Race to make 50 clears of 10 or 20. Spot each combination quickly and beat your best clear time.
  
• ENDLESS — A score attack with no finish line. The board rises faster as your LEVEL increases. Keep clearing until GAME OVER and aim for the highest score you can.
