Teach the Cast
Some of LatticeForge’s cast are still learning. When you teach them, YOU learn it best — catch what they get wrong, then quiz them.
Teach Onlie
You be the teacher — Onlie is still learning. Helping Onlie figure it out is the practice. (Only for you; nothing is saved.)
Teach the connections
Show how the logic-grid puzzles connect
You've helped them one at a time. The real understanding is how the ideas CONNECT — teach that next.
Onlie (Sudoku — the Latin-square rule: each number once per row, column, box) × Cage (KenKen — an arithmetic cage on top of a Latin square)
What rule does a KenKen (Cage) share with a Sudoku (Onlie) before its cages even matter?
Onlie then says: “In KenKen you can repeat a number in a row as long as the cage's math works out.” — is that right?
The link: KenKen = Sudoku's uniqueness rule + arithmetic cages — Cage stands on Onlie.
Latin square first, then make the cages add up.
Chevron (Futoshiki — < and > flags force the ORDER between neighbours) × Serra (Skyscrapers — edge clues count how many towers are VISIBLE)
A Skyscrapers clue says 'you see 3 towers from this edge'. How is that secretly a Chevron-style ordering clue?
Chevron then says: “A Skyscrapers visibility clue tells you the exact heights directly, with no ordering reasoning.” — is that right?
The link: both puzzles are Latin squares cracked by ordering — one states the inequalities, one hides them in a view.
Order the cells — stated, or seen.
Capstone — solve one puzzle pack together
Three grid puzzles, three deductions. Bring in the cast member for each.
Fill so each number appears once per row, column, and box. Who?
Who do you bring in?
Fill a fenced region so its numbers hit the target with the given operation. Who?
Who do you bring in?
Read edge numbers telling how many cells fill each run, then fill the overlap. Who?
Who do you bring in?
The synthesis: enforce uniqueness, satisfy the cages, and deduce from the run clues — three grids, one logical habit: find the forced move.
Unique, caged, counted — every grid hides one forced move.
