▼ Six puzzle types, as many as you like

・Number Grid … The classic number puzzle: fill every row, column and 3×3 block with 1 to 9
・Nonogram … The picture logic puzzle: use the number clues to fill cells and reveal a picture
・Sum Cross … Place 1 to 9 so each run adds up to the given total
・Number Pair … Connect matching numbers with lines that never cross or branch
・Loop Puzzle … Connect the dots to draw one single closed loop
・Paint Islands … Shade cells black to form white islands of the given size

Focus on one type or switch every day; the choice is yours.

▼ Pencil-and-paper feel, tap-and-swipe controls

Enter a number, fill a cell, draw a line: every action is a tap or a swipe. All the feel of solving with a pencil and eraser, right on your phone.

▼ Learn by doing

Each puzzle type has a hands-on tutorial on a real board, so the rules and the reasoning click right away.

▼ Five difficulty levels

・Easy ・Normal ・Hard ・Expert ・Pro

Start with Easy; clear a few puzzles and the next level unlocks. Higher levels award more points and coins!

▼ Daily Challenge

One special puzzle every day, chosen from your favorite puzzle types at a difficulty that matches what you have unlocked.

A time limit adds just the right amount of pressure. Your calendar marks every day you complete the challenge, so your progress is always in view.

▼ Streak bonus: the longer, the better

Play every day to build your streak and multiply your point rewards.

・3 days … ×1.1 ・7 days … ×1.2 ・14 days … ×1.3 ・30 days … ×1.5

"Just one puzzle today" quickly becomes a daily brain training habit.

▼ Rankings and leagues

Points from your clears count toward a monthly ranking, grouped into leagues so you compete with players at a similar level.

・Normal ・Bronze ・Silver ・Gold ・Platinum ・Master

As your total points grow, you move up and meet new rivals.

▼ Stuck? Hints and checks are one tap away

Use the coins you earn from clears for hints and answer checks. No more getting stuck: finish every puzzle with your own hands.
