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…

• …build a working CPU starting from a single NAND gate.
• …design your own instruction set, choose the opcodes, and write programs in your own assembly language.
• …install a keyboard, monitor, sound, network, and a file reader that can pull bytes from your real computer into the simulated machine.

In this game, you can…

• …push a box into itself, push it out of itself, and walk out of a box while still remaining inside it.
• …create loops where box A is inside box B is inside box C is inside box A again, then use the cycle to move things.
• …turn paradoxes into the actual solution, including puzzles where you use infinity as a tool you can manipulate.

In this game, you can…

• …cram a working gadget into absurdly tight code limits, like 9 or 14 instructions, until every single word matters.
• …build your own devices in the sandbox, including full games people recreate inside it, like in-game Tetris.
• …wire up microcontrollers, memory, logic chips, and LCDs, then write tiny assembly programs where each instruction can run conditionally.
