RULES:

Normal Schrödinger rules apply.

The value of a cell is the sum of its digits.

The grid is partially covered in fog. Correctly placing individual digits may clear some cells and reveal additional clues (no guessing is required). Cells that contain two digits will never reveal fog.

The two cells at the ends of each Parity Counter line indicate the number of odd and even values in that line, including the end values themselves. One cell counts odd values; the other counts even values.

A BitClock is a group of five cells: a central arrow cell and its four orthogonally adjacent neighbours (up, right, down, left). The arrow shows where the pattern starts and the pattern is then read clockwise around the four neighbours. The cell in the central arrow cell tells you the odd/even pattern of those four neighbours, using a simple 4-bit code. In those neighbour cells, an even value means the “bit” is ON; while an odd value means the “bit” is OFF. Each arrow cell value has its own fixed 4-bit pattern [see table below] (e.g. if a 0 and 3 are placed in an arrow cell, it would sum to 3 and its code would be OOEE. Starting from the direction of the arrow and reading clockwise, the four orthogonal neighbours must be Odd, Odd, Even, Even).

Value Codes:
0 → OOOO
1 → OOOE
2 → OOEO
3 → OOEE
4 → OEOO
5 → OEOE
6 → OEEO
7 → OEEE
8 → EOOO
9 → EOOE
10 → EOEO
11 → EOEE
12 → EEOO
13 → EEOE
14 → EEEO
15 → EEEE

INTRODUCTION:

---

Based on the logic of Jonesy. I knew right at first sight where the logic needed to go next (and that was directly into an S-Cell puzzle).

Thank you so much ChinStrap and Justin (Vitanza a.k.a. vitaminz) for your testing and feedback.

Have fun!
