Tricky Test 2 Level 64

Overview

• Difficulty: Regular
• Estimated moves: 2

The screen shows a simple on-screen calculator with a numeric keypad (digits 0–9, a decimal point, a "delete" button, and an "enter" button). The prompt at the top reads "Enter the biggest possible number for this calculator." The calculator display is empty at the start, and the keypad looks like an ordinary pocket calculator. The trap is that the screen tricks you into thinking you must type the largest finite number you can imagine (for example, a long string of 9s). In reality, the biggest possible "number" on this calculator is not a finite digit string at all — it is infinity. The game hides that infinity behind a small visual gesture you have to discover.

Step-by-Step Solution

1. Tap the 8 key on the keypad once. The digit "8" appears in the calculator display. You only need a single 8; do not type any other digits.
2. Place two fingers on the "8" now shown in the display area.
3. Twist/rotate the "8" by roughly 90 degrees using a two-finger rotation gesture (turning the upright 8 onto its side).
4. Observe that the sideways 8 instantly transforms into the infinity symbol (∞) in the display.
5. The level auto-completes as soon as the infinity symbol appears; you do not need to press "enter."

Strategy & Reasoning

The puzzle is a visual pun. An upright numeral "8" rotated ninety degrees is exactly the shape of the infinity symbol (∞), which is by definition larger than any finite number. The game rewards you for realizing that "the biggest possible number" is not about typing more digits — it is about the concept of infinity. If you instead try to string together many 9s, the calculator will only accept a limited number of digits and you will never beat the intended answer. The reason the game shows you a keypad at all is to misdirect you: it makes you think the solution is a numeric input, while the real answer is a shape transformation. Rotating the 8 is the only gesture that produces an unbounded value.

The on-screen calculator deliberately looks like a real pocket calculator with a delete and enter key, which primes you to expect a normal arithmetic input. The hearts at the top show you have several attempts, but the correct gesture is not something the keypad can express. Once the sideways 8 appears as ∞, the game recognizes the largest conceivable value and immediately advances, which is why no enter press is needed. The insight transfers to other Tricky Test 2 levels: whenever a prompt asks for the "biggest" or "smallest" something, think about abstract or visual answers rather than literal numbers.

Tips & Common Mistakes

• Typing a long string of 9s or 8s. This only fills the display with a finite number; it will never be accepted because infinity is always bigger.
• Trying to press "enter" after typing a number. There is no finite correct answer; pressing enter on any typed digits will fail.
• Forgetting to use two fingers. A single tap or drag on the 8 does nothing. You need a genuine two-finger rotation/twist gesture on the digit itself.
• Rotating the wrong amount. A small tilt will not register; turn the 8 a full quarter-turn (90 degrees) so it lies on its side.
