How does the pack builder work?
Everything happens on your device. When you press Generate, your browser creates each LITS grid from the pack seed, solves it to make the answer key, and lays the pages out as a PDF. Nothing is uploaded and there is no account. Four 5×5 or 6×6 grids share a sheet, and two 8×8 grids share a sheet. Tick Large print if you want one big grid per page. 5×5 and 8×8 come in easy and medium. 6×6 is medium only. There is no hard band, and there is no 7×7, 9×9, 10×10, or 12×12. Each puzzle prints with its number and seed, so answers line up even when you keep them in a separate PDF. The same seed and settings always give the same puzzles. Use Copy share link to send a class or a friend the exact same pack, or press shuffle for a fresh set.

About these LITS packs
Print a LITS (nuruomino) pack and solve it with a pencil. The board is split into regions. Thick lines are the region borders, and thin lines are the cells inside a region. Shade exactly four cells in each region so they form one tetromino: an L, an I, a T, or an S. A square of four cells is not a piece. The J turn counts as L, and the Z turn counts as S. Two pieces of the same shape must not share a side. The shaded cells of the whole board must join into one group, and no 2×2 block is fully shaded. A dot means you already know that cell stays empty. The answer key fills the shaded cells. It does not print dots, and it does not print a letter on a finished piece. Each file is a black-and-white booklet. Puzzle pages show the regions. The answer key starts on its own page. Packs cover 5×5 easy and medium, 6×6 medium, and 8×8 easy and medium. There is no hard band, and there is no 7×7, 9×9, 10×10, or 12×12. A 5×5 or 6×6 sheet holds four puzzles. An 8×8 sheet holds two. Tick Large print for one big grid per page. Seeds are fixed, so the same download always has the same grids. Each single pack has eight puzzles. The starter pack has five puzzles, one of every size and difficulty that ships: 5×5 easy, 5×5 medium, 6×6 medium, 8×8 easy, and 8×8 medium. To try one grid on screen first, open LITS and use Print or Download PDF there.
