River Crossing IQ

River Crossing IQ is a logic puzzle game centered on transporting characters across a river while working within boat-capacity limits, different crossing times, and other stated constraints. Each level presents a compact planning problem in which the order of crossings affects whether the group can reach the target within the required conditions.

Balancing boat capacity and crossing times

The core rule is that the boat can carry only a limited number of characters, with typical scenarios allowing two people at once. Characters may also move at different speeds, so selecting who crosses together and who returns the boat becomes part of the puzzle. A solution therefore depends on coordinating individual travel times rather than simply sending everyone across in sequence.

Some levels add time limits, making the same transport objective a timed logic test. The source describes puzzles ranging from short sequences to problems that require backtracking and several connected decisions. Classic river-crossing examples and variations introduce familiar patterns before asking players to apply the underlying logic to new arrangements.

Touch controls and correction tools

Players use touch input to select characters and the boat, drag to indicate a crossing, or complete moves through simple tap sequences. Each crossing supplies visual and numerical feedback. This makes the result of a move clear while leaving the main challenge in choosing the next valid action.

Hints can be requested when a solution is unclear, and an undo option allows earlier moves to be reversed. Hints are also described as optional, with a setting to disable their visibility. Together, these tools support experimenting with a sequence without requiring the whole level to be restarted after every mistaken decision.

Chapters, timing, and replay

River Crossing IQ contains two chapters and 70 levels. Early puzzles introduce the central crossing rules, while later stages combine constraints, tighter time budgets, and longer sequences according to the supplied description. Each level can be revisited to work on its completion time or score, so replay is tied to refining an existing solution as well as progressing through the chapters.

Level-based scoring considers completion time, hint use, and move efficiency. The game also provides an IQ-style performance gauge intended to show progress across sessions. These measures give separate feedback on speed, assistance, and the number of actions used, without changing the basic river-crossing objective.

Presentation and settings

The interface uses readable text, high-contrast presentation, concise instructions, and touch targets sized for comfortable tapping. Sound and animation preferences can be adjusted, while animations communicate crossing results without being the stated focus of play. The game is designed for short puzzles as well as longer problem-solving sessions.

Sharing tools can export a score or summary image through the device's standard share sheet. The source describes this as an optional local sharing action. The game is focused on single-player solving, and its levels are described as deterministic, so repeated attempts use performance and approach rather than network competition as the basis for comparison.
