RackSwap NumGridCard

Features
Read full description

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.

About

Cloudline Circus

Read full description

Cloudline Circus is a single-player card strategy performance set above the clouds. Each hand is a stage instruction: build a routine, protect the three-ring venue, and keep the aerial line moving from one act to the next. PLAN A WHOLE PERFORMANCE A complete 52-card pack drives every decision. Pairs raise temporary guardrails, three of a kind strengthens one ring, straights carry the company across the stage, flushes light an entire suit team, and a full house brings all three rings into a shared curtain call. Every rank and suit stays readable while the pace of the bill changes. DEFEND THE THREE RINGS Read the stage call, choose which cards to hold, and decide where each routine lands. Scene-stealing performers, misplaced props, lighting faults and changes of scene alter what is worth keeping in hand. A strong local move can settle one ring; a coordinated show can keep the whole venue in motion. ROUTE THE FLYERS Trapeze Chain turns consecutive card ranks into a working aerial route. One-way rings, broken ropes, matched timing marks and cards fixed to the line make every crossing a planned sequence. Ace rules are printed before the act begins, so no hidden rule changes how the route can be solved. FOLLOW THE PROGRAM Program orders add clear goals to each performance: repeat a hand type, preserve a suit, finish under a fixed number of plays, or close on a particular routine. These objectives reward timing and restraint rather than faster tapping. BUILD A PERSONAL TOURING SEASON Travel across six cloud cities, each with its own run of stages and handcrafted rule combinations. The Program Book keeps the bills and completed orders together, the Deck Album exposes all four suits at a glance, and the Bestiary introduces the face-card company. The Photo Studio can place one of your own photos inside the card-back frame and create a show poster stored on your device. DESIGNED FOR FOCUSED PLAY The interface is landscape-first and built for iPhone and iPad. Rules are visible before play, progress is stored locally, and the core experience can be completed offline. Cloudline Circus is a game of planning, not chance: there is no wagering, no cash or prizes, and no casino or token economy.
