RackSwap NumGridCard

RackSwap NumGridCard delivers two distinct card-based logic experiences in a single app, each built around spatial reasoning and numerical strategy.

In Card Rack mode, you face a board of nine shelves with four spaces each. Cards are stacked behind one another, and only the front card can be moved. Drag a card onto an empty space to reposition it, or drop it onto another card to swap the two. Collect all four suits of the same rank onto one shelf to clear it. Every level is seeded so the same puzzle appears for every player, while the move budget and difficulty curve tighten as you progress through 60 handcrafted stages.

In Tens Grid mode, a large numbered grid is dealt from a standard deck. Draw a rectangle around any group of cards whose values add up to exactly ten and they vanish. The goal is to clear as much of the board as possible using spatial awareness and arithmetic, with limited shuffles available when no rectangle works.

Key features that set RackSwap NumGridCard apart:

- Dual game modes with fundamentally different mechanics sharing one polished interface.
- Deterministic seeded levels ensure fair competition: every player solves the same board.
- An internal solver verifies each generated puzzle is solvable and assigns a par score, so star ratings reflect true skill.
- Undo, shuffle, and hint tools let you experiment without penalty while still rewarding efficiency.
- A progressive 60-level campaign that gradually introduces deeper stacks, fewer free spaces, and tighter move budgets.
