Tonight's net
My catches
No catches yet. Cast a net before he runs: one of the chip's 4,000 drops is yours.
My net NFTs on Sepolia
How it works
- The door. Every night Squeektoshi, a real hamster, runs his wheel on Squeekchain. His run becomes a program for a real IBM quantum computer.
- The shake. At 13:00 the quantum computer runs it 4,000 times. Each run is a drop through the door that lands on one of 16 hamsters. Why wait? Until then your hamster is in every universe at once.
- Your net. One of the 4,000 drops is yours. The hamster it lands on is your catch. The rarer the hamster, the stranger its universe.
- Got away? Some drops land where no hamster can be. Then your hamster slipped back through the door.
- The fuel. The door only opens for SQK. Every net burns 0.01 test SQK forever. So far the door has eaten 0 SQK.
Cast your net before 22:00 your time. A net is a test NFT on Sepolia. Nobody picks a hamster.
What you need: a crypto wallet on the Sepolia test network, 0.01 test SQK (free here, once per night) and a little free test ETH for the fee (get free test ETH). Test tokens: no money value. One net per wallet per night.
- Why 16 hamsters?
- The quantum program keeps his place on the ring in 4 qubits, and 4 qubits give exactly 16 different answers: one per hamster.
- Why 4,000 drops?
- A quantum computer gives a random answer each time, so it runs the same program 4,000 times. Each run lands on one hamster: one drop. Hamsters with few drops are the rare ones.
- Which drop is mine?
- After the result is posted, the contract draws one of the 4,000 drops for your net at random (a fingerprint of the night's result and your net's number). Nobody can choose it or know it before.
Ten trait slots
- Your net also gets one drop for each of its hamster's 10 trait slots: face, head, eyes, mouth, neck, hands, back, special, aura and background.
- Where a slot's drop lands decides it: a common spot or chip noise leaves the slot empty, a rarer spot gives a rarer item, and Legendary items come only on a golden night (about 1 night in 16 to 20).
- Anyone can recheck every trait from the night's posted numbers and the published result file, and the draws wait for the next Sepolia block after the post, so nobody knows them before.
| Each slot | Nothing | Uncommon | Rare | Epic | Legendary |
|---|---|---|---|---|---|
| Chance | 64 in 100 | 23 in 100 | 7 in 100 | 6 in 100 | ~1 in 260 |
The least-visited spot he could reach is Epic; if the chip's very first look landed there, it is Legendary.

The ring
Each of the 16 hamsters has its own look: its number's 4 bits pick a party hat, glasses, a scarf and a grin. He starts at his own spot (the dashed tile), set by his total turns, so nobody knows it before he runs. On a short night he can only reach spots near his start; drops elsewhere are chip noise, and a net whose drop lands there gets away.
Check it yourself
Every number here is public. This night:
The recipe in 6 lines
- Read his turns per active 10-minute round from SqueekCore roundPage on Sepolia (12:00 to 12:00 UTC).
- One step per round. Too many rounds: even groups, mean turns rounded half up (at most 16 steps up to 4 Nov, recipe v1.1; at most 10 from 5 Nov, recipe v1.2, which also runs with noise protection).
- Coin tilt = π × min(turns, 700) / 700 (an RY turn of the coin qubit).
- Start at his own spot: total turns mod 16. Coin (|0⟩ + i|1⟩)/√2. Each step: tilt the coin, then coin 1 steps +1, coin 0 steps −1, on a ring of 16.
- IBM runs it 4,000 times. A spot is in reach that night if (spot + total turns + steps) is even and it is at most as many spots from his start as he took steps; out of reach: he got away. A spot in reach with at least 1% of the landings is caught; rank those by landings: the fewest is Epic (Legendary if the chip's very first shot landed there), the next Rare, the two after that Uncommon, the rest Common. The spot's 4 bits pick the looks.
- Each net gets one of the night's landings: keccak256 of (the night, the posted result's hash and job id, the net's token id) modulo the number of landings, counted off spot by spot from spot 0. If that spot is caught, the net catches its hamster with its rank; if not (out of reach, or under 1%), the drop was chip noise and the net got away.
- Each trait slot k = 1 to 10 (face, head, eyes, mouth, neck, hands, back, special, aura, background) gets its own landing the same way, keccak256 of (the night, the seed, the token id, k) modulo the landings; that spot's rank is the slot's tier (Common or chip noise: the slot stays empty). The contract's dnaOf gives each slot's tier, landing and hash; its renderer turns them into the picture (the pictures can change until the contract is locked).

Rebuild it
Proof stamp: the twin test
Each chip job also plays a card game with two linked qubits that cannot talk. Any fixed plan wins at most 75% of rounds.
Play it yourself: can a plan beat 75%?
Each round, twin A and twin B each get a card, FUR or HAT, and answer 0 or 1 without seeing the other's card. They win if they answer the same, except when both got HAT: then they must answer differently. Give them a fixed plan (tap an answer to flip it):
Squeektoshi's wheel runs are measured by Squeekchain and settled on Sepolia in 10-minute rounds.
A normal computer can simulate this small walk. What is real is that every chip result shown here ran on real IBM hardware, with real noise, on his real run. Chip runs whose twin test scores under 79% are thrown out and redone, and each one is listed on its night.
A demonstration on one chip, not a lab-grade test.
