If we ASSUME you have a 3V supply, then you need to put a 33Ohm resistor on EACH led.

If you have a 9V supply, you can put 3 leds in series with a 90 Ohm resistor, and you should find that 3 chains of LEDs look much more evenly lit

but chains of three only gives me 9 i need 10 easly lit thats my problum would the 3V light them all bright

The maths for 10 doesn't work, unless you have one little lone one, with a different resistor.... If you do, use the33 Ohm I said before. Or, use 12 LEDs instead.

What battery are you using. 2 AA batteries will be the best for it

This. Without the battery voltage, it would be impossible to recommend a resistor. 2AAs should be able to run most LEDs directly. Google "LED resistor calculator". You will also need the current draw of the LEDs, which is usually about 20-30mA.

You need a resistor for each LED, or they will die.
