Is it cheating to use undo or hints?

This one comes down to what you're playing for. There's no solitaire police - only the standard you set for yourself.

Quick answer: No. Undo and hints are learning tools, not cheating - they let you explore lines of play and understand why a deal is won or lost. If you want a pure test, play without them, but nothing stops you using them casually. Leaderboard times naturally reward players who solve cleanly and quickly.

Why they're not cheating

Undo and hints turn solitaire into a puzzle you can study. Rewinding a dead-end line teaches you why it failed; a hint points you at a move you'd have found with more experience. For learning a new variant - say FreeCell or Spider - they dramatically shorten the path from confused to competent.

When you might skip them

If you want a clean test of skill, play a deal start-to-finish with no undo and no hints - especially on the daily challenge or in multiplayer, where a single confident run is the whole point. That's a personal choice, not a rule.

What the leaderboard rewards

Ranked times naturally favour clean solves: hesitating, undoing and re-planning all cost seconds, and ties break toward fewer moves. So even though undo is always available, the leaderboard quietly rewards the players who don't need it.
