PS1 Puzzle Games: Intelligent Qube and Devil Dice Compared
For a PS1 puzzle game about anticipating an approaching formation, choose I.Q.: Intelligent Qube. For a puzzle built around manipulating and matching dice, choose Devil Dice. Both use simple-looking objects to create problems that demand more thought than the screenshots suggest.
These are focused alternatives to the long campaigns in our PS1 games guide. The useful distinction is whether you prefer planning around incoming pressure or arranging objects into the result you want.

Intelligent Qube: plan the capture and your escape
In Intelligent Qube, large cubes roll towards your character across a grid. You mark positions and capture cubes while trying to avoid being pushed into danger. Certain captures can create opportunities to clear a larger area.
The first question is spatial: where will the formation be after its next movement? The second is personal: where will your character stand? Solving the cube pattern while leaving yourself no room to move is not a complete solution.
For an early attempt, trace a safe route before committing to a capture. If you fail, identify whether the capture was poorly placed or whether you simply stood in the wrong place. Those mistakes can look similar on screen but need different corrections.
Devil Dice: think about the result of each roll
Devil Dice, known as XI in Japan, puts a small character on a field of dice. Matching sets clears dice from the playfield. The physical act of rolling a die means a move can change both its position and the face you are trying to use.
Pick it if you like manipulating a system rather than responding only to a single incoming pattern. A tempting immediate match can affect the arrangement you need next, so it is useful to think one operation beyond the current move.
Practise a small arrangement until you understand how the faces change. Do not begin by trying to fill the entire board with a spectacular chain. A reliable short sequence gives you something you can intentionally extend.
Which style is more likely to suit you?
Choose Intelligent Qube when you enjoy seeing a threat approach and planning a precise response. Choose Devil Dice when you enjoy building a pattern and changing the board yourself. Neither game is simply a slower substitute for action: both can demand quick decisions once the situation develops.
If you prefer a puzzle where the viewpoint itself is the problem, our PSP puzzle guide offers another direction. If you want long-term unit growth and deliberate battle planning, look at PS1 tactical RPGs instead.
How to judge the first session fairly
Give yourself a few attempts whose only purpose is understanding the rule. On the first, observe what changes after one action. On the second, predict the change before making it. On the third, try combining two actions you already understand.
A rising score is one kind of progress; being able to explain a failure is another. If you can identify the exact placement or movement that caused a problem, the next attempt can test a solution. If you only remember that the board became chaotic, slow down and choose a smaller learning target.
Do not compare the games solely by how far you get in the first ten minutes. Familiarity with one puzzle vocabulary can make its opening feel easier without making it your preferred game over time.
Names, editions and playing on iPhone
Intelligent Qube is also associated with the regional title Kurushi. Check the full title because sequels and later rereleases can have similar names. Devil Dice’s Japanese name XI can likewise make a library entry look unfamiliar.
