Bunnydoku Double Bunny Mode: Rules & Solving Tips

Two little bunnies, one lovely logic challenge! 🐰🐰 Double Bunny asks for two bunnies in each row, column and colored region, all safely apart. It is a solo puzzle mode, not a two-player game. Let’s find room for every pair.

🐰🐰 The Double Bunny rules

These are the rules described in Bunnydoku’s official Double Bunny announcement on Google Play. If the one-bunny rules are new to you, start with our Bunnydoku tips before switching modes.

• Each row needs exactly two bunnies.
• Each column needs exactly two bunnies.
• Each colored region needs exactly two bunnies.
• No two bunnies may touch horizontally, vertically, or diagonally.

🔢 Track how many bunnies each group still needs

For every row, column, and region, subtract the confirmed bunnies from two. A group with no bunnies needs two more; a group with one needs one more; a group with two is complete. You may exclude every other cell in a completed group. After the first bunny, exclude its touching neighbors, but keep considering the distant cells in its row, column, and region.

This is the biggest habit to change from classic mode. Crossing out an entire row after its first bunny removes the very cells you need for the second one. Check all three counts after each placement, because a move can complete a column while leaving its row and region unfinished.

🧩 Look for compatible pairs, not just two empty cells

Two available cells are useful only if they can both hold bunnies without breaking a rule. If an empty region needs two bunnies and has exactly two remaining candidates, both are forced only when they do not touch and their row and column counts permit them. If they touch, the board has a contradiction: revisit the deductions that left those two cells.

With three candidates, list the pairs. A row that still needs both bunnies and whose only candidates are three consecutive cells has just one non-touching pair: the outer two. The middle candidate cannot be used because it would block both of the others. This turns a count of three possibilities into two forced placements.

🔎 Use the 2 × 2 limit

Any 2 × 2 block can contain at most one bunny. Every pair of cells inside that square touches along an edge or a diagonal. Four empty cells therefore do not mean four usable spaces—or even two. If all candidates for a region that still needs two bunnies fit inside one 2 × 2 block, something earlier is wrong. This space check is especially useful around compact regions and board corners.

🥕 Compare required bunnies with shared capacity

Suppose two regions have no confirmed bunnies and all their candidates lie in the same two rows. Those regions need four bunnies in total; the two rows also hold four. Together, the regions must use all of that capacity, so candidates from other regions in those rows are excluded. The same reasoning works with columns. This deduction reserves space without choosing the individual bunny positions.

For each next move, ask two questions: how many bunnies are still needed, and how many can actually fit? Counting plus the no-touch rule gives you more information than either alone. To see how Double Bunny fits into the wider game, read Meowdoku vs Bunnydoku.

Two bunnies can look like a lot at first. Start with one small group, check its count, and enjoy each little discovery. 🥕
