RULES:

---

Normal Sudoku rules apply.

• Renban (pink): Digits along each Renban line form a set of consecutive, non-repeating digits in any order.
• Nabner (purple): Digits along each Nabner line form a set of non-consecutive, non-repeating digits in any order (e.g. if a 3 appears on a Nabner line, then 2 and 4 cannot appear).
• Tens (gold): Digits along each Tens line consists of one or more contiguous groups of cells, each of which sums to 10. These groups of cells cannot overlap.

• Minimum/Maximum: Digits within an Inward Arrow cell must be less than their orthogonal neighbours.
• Odd/Even: Digits within a Circle cell are Odd; digits within a Square cell are Even.

MODIFIER:

• Shenanigans!: Each line is one of the above constraint line-types but some are lying to you (i.e. they must satisfy one of the other line-types and not the presented colour). The wrong-coloured lines are exactly those lines which have the digit 'D' on them ('D' must be determined by the solver).

INTRODUCTION:

---

If you're thinking "have I seen this puzzle before?" you're right, or at least partially right. This is a greatly improved version of a previous release, after having received some wonderful insight and advice from other setters. This version should be a lot more accessible.

The Nabner and Tens lines were initially developed by zetamath I believe, though I found them through other setters, with the constraint found in "Shenanigans" by Jay Dyer. I would say go check out their puzzles (which you should!) but they need no introduction from me.

Here are the other entries in the "Shenanigans!" series, for those interested:

Here are some puzzles from other setters using the same constraint:

Have fun!
