In this game, you can…

• …move like chess pieces, then watch them fall under gravity until they land.
• …stack chess pieces into improvised towers to climb out of pits.
• …pick your own starting pieces, so solving begins before the first move.

In this game, you can…

• …plan a full path where you're never allowed to step on the same square twice.
• …watch enemy pieces stack on the same square at once, even though that's not how normal chess works.
• …draw your king's entire route to an orange goal while every enemy piece advances at the same time each second.

In this game, you can…

• …activate pressure plates that physically move chunks of the board before you can even route the King.
• …chain multiple switches by triggering and releasing plates in the correct sequence to reshape the level.
• …uncover hidden target squares and pressure plates buried under other pieces, then maneuver the right piece onto them.

In this game, you can…

• …solve Sudoku grids that start with as few as two given digits, using logic instead of guesswork.
• …apply king and knight move restrictions so a number can't repeat a chess move away, even across the grid.
• …place a number near a block edge and instantly narrow that same number in the neighboring block down to two possible cells.

In this game, you can…

• …solve every puzzle by deduction without ever needing to guess.
• …use bracket and dash symbols that tell you whether blue cells in a line must be consecutive or separated.
• …click a number outside the grid to strike through an entire row once you've ruled it out, changing how you work the board.

In this game, you can…

• …play a mode where the lines you draw are permanent, so every route becomes a long-term commitment you can't undo later.
• …pause constantly to pick up trains, drop them at problem stations, and build temporary one-stop lines to bleed pressure off the map.
• …watch trains make smart decisions, dropping passengers at interchanges to transfer instead of taking everyone on pointless loops.

In this game, you can…

• …use teleport blocks in reverse to reach places that look impossible at first.
• …bounce off corner blocks to stop short, pivot, and take a completely different direction.
• …launch a cube off the screen with one wrong move and instantly restart the level.
