A walk through on the false ADJE pattern I produced:

Requirements1) An Almost Double JExocet with 4 digits

2) Only one base digit should eventually be capable of being true three times in the partial fish cells.

3) One of the mini-lines along the JE band must contain a target cell and two cells that can't contain a base digit.

- Code: Select all
` *----------------*-------------------*-----------------*`

| abcd abcd / | . . . | . . . | abcd = base digits

| . . . | . / . | abcdx / / | x = any other digit

| . . . | . abcdx . | / . . | / = no base digit

*----------------*-------------------*-----------------*

If r3c5 holds a base digit, the same digit must be true in r2c7 because r2c89 are unavailable - which makes the JE false.

It's therefore impossible for the two target cells to hold different base digits.

So the second true digit in the base cells must be true in r2b2 and r3b3.

With an ADJE, this requires this digit to be true in both sets of base cells, and therefore false in all four target cells.

In turn this requires this digit to be true 3 times in the partial fish cells and be the single spoiler digit.

Taking (a) to the single spoiler digit, the following pattern is now forced.

It results because (b) (c) & (d) can only be true in two partial fish cells, and must each occur at least once in b1c3,b2c5,b3c7

- Code: Select all
` *----------------*-------------------*-----------------*`

| ab ab / | . dx . | cx . . | abcd = base digits

| . . dx | ac / ac | bx . . | x = any other digit

| . . cx | . bx . | / ad ad | / = no base digit

*----------------*-------------------*-----------------*

Inferences & Eliminations:1) In three mini-rows (a) occurs with a different base digit in each box together with a non-base digit.

Therefore any non-base digit in the cells shown with (a) as a candidate can be eliminated

2) In six mini-rows one of the other base digits occurs with two non-base digits.

If one cell must contain a base digit

a) all base digits can be eliminated from the other two cells

b) any base digit eliminated from that cell can be eliminated from two other mini-rows on the repeating diagonal

3) The cell pairs containing (bx), (cx) and (dx) must each contain one instance of a base digit

If a non-base digit must be true in one of them,

a) any non-base digits can be eliminated from the other.

b) the partial fish cells for the base digit must now contain two truths which may allow other eliminations

4) The spoiler digit (a) must be true 3 times in the partial fish cells, and so may be restricted to certain base digits.

If one of the cells in the pairs (ab), (ac) or (ad) contains a digit that can't be the spoiler, the other cell can only hold a potential spoiler.

There will also be inferences available for the non-base digits in the JE band as three of them form repeating pairs with different members of (bcd), but generally these will be trivial.
