Fill numeric grids to satisfy horizontal and vertical equations using drag-and-drop number tiles, a loop that trains speed and logical reasoning. CrossMath Master: Grid Puzzle is made by Baiduca for Android puzzle players, pairing a 7,000-level campaign with an endless random-board Free Play mode. The app includes difficulty tiers, light and dark themes, and on-screen tools such as hints and undo, making it suitable for students practicing math and adults seeking short brain-training sessions.

This grid puzzle blends crossword structure with arithmetic problem solving

In this game, you place numbers into empty cells so that both rows and columns form correct equations. The core loop requires basic arithmetic: addition, subtraction, multiplication, and division. The Campaign contains over 7,000 hand-crafted levels that present designed challenges, while Free Play generates unlimited random boards for continuous practice. The rules enforce correctness across two axes, which forces players to consider the grid as an interlocking system rather than isolated sums.

Modes and mechanics give both guided progression and endless practice

In this game, players progress through three difficulty tiers labeled Easy, Medium, and Hard, which scale challenge according to the source material. The app supplies a pool of numbers to drag and drop into slots, and offers an undo function plus a hint that reveals the next step. Campaign mode advances through hand-crafted puzzles, while Free Play produces randomized boards that keep sessions unpredictable and extend play beyond the main progression.

The visual design and tactile feedback shape focus during play

In this game, a Neobrutalist visual style uses high-contrast, vibrant graphics and both Light and Dark themes for comfortable viewing. The interface presents a clean grid and a separate number pool, keeping input gestures simple. The app adds immersive haptic vibrations during interactions to create tactile confirmation of moves, and progress statistics track session data so players can monitor improvement over time.

Difficulty curve and replay drivers suit deliberate practice and casual sessions

In this game, onboarding is handled through difficulty tiers rather than an extensive tutorial, so new players adjust by starting on Easy. Replayability comes from two sources: a large library of curated levels for staged progression and an endless random mode for short, repeatable plays. The combination suits users who want measurable improvement as well as those seeking occasional mental warm-ups.

Recommended for focused practice and repeat short sessions

The game fits players who want arithmetic practice embedded in a grid-based puzzle format; it supports measured skill tracking and both curated and infinite play options. However, the app follows a free distribution model that includes in-app advertisements reported by users, which may interrupt short sessions. For learners and casual puzzlers who accept occasional ads, the game is worth trying as a daily mental exercise.
