Every phase asks for a longer equation than the last, starting at just 3 cards and building to 10. Clear all the phases to win. It's designed to be winnable but tight: a sharp player will win often, a careless one will get stuck.

WHY IT'S DIFFERENT
• Real math, not "close enough." Every completed equation is checked for validity — proper PEMDAS order and correct multi-digit numbers.
• Every placement is a commitment. Cards you play can never leave the board, and slots fill in from the ends only. One rushed move can cost you the round.
• Escalating challenge. Early phases teach the basics with simple comparisons; later phases demand multiple operators, parentheses, exponents, and factorials.

FREE TO PLAY
• 8 escalating phases of solo play, start to finish
• The Regular symbol set (+ − < > =)
• Combine = onto < or > to make ≤ and ≥
• Wild cards you declare on play
• A Challenge round every four hours, with an archive of past ones
• Training mode for drilling your arithmetic facts
• A daily play streak and daily objectives
• High scores, drag-and-drop placement, and a full tutorial

PRIVACY
No ads. No analytics. No account. Your progress never leaves your device — the only thing that does is what Google Play and RevenueCat need to sell and restore the Pro unlock.

Equations is a quiet, thinky game you can pick up for one round or many. If you like solitaire, number puzzles, or games that reward planning over luck, give it a try. ## Rankings - #3,158,884 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.INTERNET` - `android.permission.READ_EXTERNAL_STORAGE` - `android.permission.SYSTEM_ALERT_WINDOW` - `android.permission.VIBRATE` - `android.permission.WRITE_EXTERNAL_STORAGE` - `com.android.vending.BILLING` - `com.android.vending.CHECK_LICENSE` - `com.lewislgc.equations.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [Equation Explorer](https://chrome-stats.com/d/com.ElimuShop.EquationExplorer) — 308 users - [Equation Builder](https://chrome-stats.com/d/com.builderhq.zzgamehezi) — 7 users - [Solitaire Math](https://chrome-stats.com/d/solitaire.game.math.number) — 41,707 users - [Equation Match](https://chrome-stats.com/d/com.sefikcevik.equationmatch) — 31 users - [X² Challenge](https://chrome-stats.com/d/com.xsquared.puzzle) — 20 users - [The Equation Game](https://chrome-stats.com/d/com.companyname.equationgame) — 6 users - [Equation Master](https://chrome-stats.com/d/com.illusionmatrix.equationmaster) — 32 users - [Math Line Rush](https://chrome-stats.com/d/com.matagigames.mathlinerush) — 38 users - [EquatePro - Math Puzzle Game](https://chrome-stats.com/d/com.equatepro.game) — 24 users - [Equate 8: A Math Puzzle Game](https://chrome-stats.com/d/com.cinqmarsmedia.equate8) — 658 users - [Math Expert: Master Equations](https://chrome-stats.com/d/hr.grafing.mathexpert) — 1,896 users - [Equation Card Swap](https://chrome-stats.com/d/com.hmyx.numlink.pulse) — 11,366 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.lewislgc.equations)
