Number Puzzle Pro Tips: The Move-Count Math Behind Every Tier

The Number Puzzle mastery guide teaches you how to solve the sliding puzzle — the layer-by-layer technique, the patterns, the endgame. This is the layer on top: how the game turns your solve into NP, and how to squeeze the most reward out of every run. It rewards one thing above all — efficiency — and it hides a genuinely counterintuitive truth in its difficulty settings: the “hardest” mode usually pays the least NP. Once you understand the single formula that runs the whole thing, your scores and your NP both jump. Here's the math.

The One Formula That Runs Everything

Every scored run is graded by a single, brutally simple equation:

Score = 1000 − (moves × 10)

That's the whole scoring engine. You start with a notional 1,000, and every move you make costs you 10 points. Solve in 20 moves and you score 800; solve in 60 moves and you score 400. Notice what's not in that equation: time doesn't score (it's only a limit you have to beat), and neither does grid size directly. The only lever on your score is how few moves you use. Every ten moves you shave off is a flat 100 points back — often an entire tier. Efficiency isn't a strategy here; it's the only strategy.

Every Tier Is Really a Move Budget

Your score drops you into a reward tier, and each tier pays a base NP amount. But because score is nothing but moves, you can translate every tier straight into a move budget — the number of moves you have to come in under to earn it:

Read the tiers this way and they stop being mysterious. “Diamond” doesn't mean “play brilliantly” — it means “finish in twenty moves or fewer.” That reframing tells you exactly what to chase on any given run: not a vague “good score,” but a hard move count. Know your budget and every extra shuffle becomes a decision, not a reflex.

The Difficulty Trap: Why Hard Usually Pays Less

Here's where most players leave NP on the table. The three difficulties each apply a flat NP multiplier — and at a glance, Hard looks like the obvious money play:

• Easy — 3×3 grid, 120s, ×1.0 NP, +25 EXP
• Medium — 4×4 grid, 180s, ×1.25 NP, +50 EXP
• Hard — 5×5 grid, 300s, ×1.5 NP, +100 EXP

A 50% NP bonus on Hard sounds great — until you remember what the multiplier is multiplying. Difficulty changes the grid, and a bigger grid takes far more moves to solve. More moves means a lower score, which means a lower tier, which means a smaller base NP for the multiplier to act on. The bonus and the penalty are pulling in opposite directions — and the move penalty wins.

Run the Real Numbers

Put realistic move counts through the formula and the ranking is stark. (Exact moves depend on your scramble and skill, so treat these as typical ranges, not promises.)

For raw NP, Easy wins outright — often by three or four times over Hard — because the small grid keeps you inside the high-tier move budgets that the multiplier can't otherwise buy. The instinct that “harder = more reward” is exactly backwards here.

So When Is Hard Actually Worth It?

Two reasons, and neither is NP. First, EXP: Hard pays +100 EXP against Easy's +25 — four times as much — so if you're leveling up rather than farming NP, the calculus flips and the big grid earns its keep. Second, the Weekly Leaderboard (it resets every Monday): leaderboard rank is about raw score, and a strong Hard finish is a bigger flex than a routine Easy Diamond. Pick your difficulty by your goal — Easy to fill your wallet, Hard to build EXP or chase rank. Just don't play Hard thinking it's the NP play, because it isn't.

Spending Your Five Daily Submissions

You get 5 scored submissions a day, and each one should count. A few rules to stop wasting them:

• Warm up in Practice first. Practice mode pays nothing — which is exactly why it's the place to get your solve clean and your move count down before you commit a scored run. Never spend a submission on a cold, sloppy first attempt.
• Match the difficulty to the goal. Farming NP? Put all five on Easy. Grinding EXP or pushing the leaderboard? Spend them on Hard. Don't split without a reason.
• Chase a move number, not a “good game.” Decide your target tier, translate it to its move budget, and treat every move past it as points bleeding out. On Easy, aim to come in under 40 (Platinum) and you're already banking 340+ per run.
• Use all five. They reset daily and don't roll over — an unspent submission is just NP you chose not to earn.

Put it together and the Number Puzzle stops being a test of patience and becomes a little optimization problem: minimize moves, pick the grid that keeps you in the rich tiers, warm up for free, and spend every submission with a target in mind. Do that and a two-minute sliding puzzle quietly becomes one of the steadier NP earners in the arcade — precisely because you stopped playing it the hard way.
