🎯 The Goal

TallyUp is a math puzzle game. Each round presents you with an equation that has three or four blank tiles and a target answer. Your job is to fill in the blanks using numbers from the pool below the equation — so that the completed equation equals the target. Solve it before the timer hits zero to earn points!

▶ How to Play

• Select a difficulty level to start the game. The timer only begins once you pick a level.
• Tap any blank tile in the equation to select it. It will glow to show it's active.
• Then tap a number from the pool below to place it in that blank.
• Tap a filled blank to remove that number and free it back to the pool.
• Use the ✕ Clear All button beneath the equation to reset all blanks at once.
• Once all blanks are filled correctly and equal the target answer, you win the round and points are added to your score!
• If your filled equation doesn't match the target, no problem. There's no penalty for wrong attempts. Keep rearranging the numbers until you find the right combination.

🔢 Order of Operations (PEMDAS)

Equations in TallyUp follow standard math rules of PEMDAS. This means the game evaluates your equation in this order:

• Exponents (^) are calculated first.
• Multiplication (×) and Division (÷) are calculated next, left to right.
• Addition (+) and Subtraction (−) are calculated last, left to right.

For example: 2 + 3 × 4 = 14, not 20, because multiplication happens before addition.

⚡ Difficulty Levels

🏆 Scoring

You earn points only for correct answers. The harder the difficulty, the more points each correct answer is worth — Easy gives 1 pt, Medium 2 pts, Hard 3 pts, and Extreme 5 pts. Questions that time out or get skipped score zero. Your running points total is always visible in the top-right corner of the screen.

⏱ Timer & Time's Up

Each round has a countdown timer that starts as soon as the round begins. The timer ring changes colour as time runs low — turning amber when 40% of time remains and red when only 20% is left. If the timer reaches zero before you solve the equation, the round ends automatically and the correct answer is revealed briefly before the next round loads.

⏩ Skipping a Round

You can skip a round at any time by pressing New Game (skips to a fresh equation) or End Game (ends your session). Skipped rounds are logged in your session history with zero points. However, there is a short grace period at the start of each round during which skipping is not logged. This gives you time to switch difficulty or settle in without accidentally counting a question as skipped:

• Easy: 5-second grace period
• Medium, Hard, Extreme: 10-second grace period

Switching the difficulty level during a round never counts as a skip. It simply starts a fresh round at the new level.

📊 Session History

Tap the 📊 button in the top-right corner at any time to view your session results. The history panel shows every question attempted during the session, the difficulty level, the correct equation, whether you got it right or it was skipped, and the points earned. It also shows your overall accuracy percentage and your points percentage versus the maximum possible. If a question was logged in error, tap the ✕ on that row to remove it from your history.

💡 Tips

• Remember PEMDAS — multiplication and division in the equation are evaluated before addition and subtraction, so the position of numbers matters more than it might look.
• There's no penalty for wrong guesses. Try every combination freely until the equation works out.
• On Extreme, you have four blanks and three operators. Think about the exponent position first since it has the biggest impact on the result.
• Use the Clear All button to quickly wipe the slate and try a completely different arrangement.
• Your session history is saved until you press New Session, so you can review your performance at any time during the session.
